Sir my name is Akshat I am from class 10th I am always confused that why an ammeter is connected in series and a voltmeter is connected in parallel also why the current divides in parallel connection and voltage divides in series connection, I have heard that the current always travels the shortest path so why does the current travels through our body (with high resistance) when we touch a live wire why does it not travels through the copper wire only isnt it the shortest path ??
Current divided in parallel connection as it has to go through two paths which is how it divides equally and voltmeter is connected in parallel as the voltage across parallel connection remains the same..
A block of mass3kg is placed on a smooth inclined plane and is connected from one end To a pulley via a light string. Another mass of 6kg is hanging from the pulley as shown in the figure. Acceleration of block of mass 3kg is (here,g is acceleration due to gravity.)
Sir, I'm a physics teacher but I had this doubt in mind and couldn't think of the answer on my own. It got cleared now and now onwards I'll teach this to students also. Thankyou so much
Sir I have a doubt.In an Ac generator,the speed at which the coil rotates is doubled. How would this affect a)the frequency of output voltage b) the maximum output voltage.
Sir im a student of class 12 science (PCB) and i have a doubt since 11th class. What actually is a phase in a wave equation of motion and how it is able to change the trajectory of 2 waves resulting in a circular path or an helical path and how when the phases are same they add up and form a bigger amplitude wave and how they cancel out if the phases are opposite
Arjun, Phase in wave is nothing but the location from where your wave started propagating, you are familiar with the equation Y=sin(kx-ωt-Φ) this is the simplest wave and easy to understand and study. here the particle is oscillating and if you do phasor analysis, you see that it is moving in circle (Don't worry about Hifi words, i've attached video link. watch that you'll understand). If your particle is starting from origin, then its phase is zero, if your particle is starting from 90 degree, then its phase is 90 degree. throughout the propagation, the phase will be constant. having phase is noting but instead of starting from origin, your particle is starting from different point. Hope it Cleared your doubt. here is the video link : th-cam.com/video/VuX_UExHa0M/w-d-xo.html
@@darsh62ok I understand now that phase defines the location of the start of oscillatoin . From a point on a graph (such as, the origin) by a certain angle .
Sir I am from 10th grade I have some confusions regarding the concept of the direction of the magnetic field in the chapter on the magnetic effects of electric current, especially when dealing with circular loops. When studying the circular loop, I learned that if the current flows in a clockwise direction, the magnetic field inside the loop is outwards direction, as determined by the right-hand thumb rule. However, I’m struggling to understand what is actually meant by the “direction of the magnetic field” in this context. Could you please explain why we focus on the direction of the magnetic field, and what purpose it serves? Similarly, I’m confused about why we use the concept of tangents to determine the direction of the magnetic field like we draw tangents on magnetic field lines. What is the significance of drawing a tangent to the field lines, and how does it help in understanding the magnetic field at a specific point?and why we do that to know direction of magnetic feld If possible, could you recommend any resources or videos that explain these concepts in a very simple and clear manner?
We use tangents to determine the magnetic field direction at that point because magnetic field lines are only imaginary lines. and show the direction of movement of hypothetical North Pole if it was free to do so. Magnetic field lines dont show the actual magnetic field direction
and regarding first question, right hand thumb rule gives direction of magnetic field lines and not magnetic field... Just like the magnet has two poles North and South. Current carrying conductor also have two faces given by clock face rule
Sir, my name is bibek mera question yeh tha ki velocity of the particle at geostationary orbit usko haam V""=√GM/R+h likh sakte hai.. where h is the height of that particle from that surface.. Suppose, humne ek lamba rigid rod length (L) and L=h to jo formula hoga linear velocity ka woh V'=(R+L)w (w= angular velocity of earth) (w=1/R√GM/R) to jo linear velocity ayega woh V'=((R+L)/R)√GM/R hoga.. toh V''=V' hoga kyuki linear velocity to same hai.. to agar dono ko solve karu toh L=h hona chahiye lekin woh nahi ho raha aisa kyu??
Sir, direction of centrepetal acceleration is considered towards centre of curvature, but not towards axis of rotation but direction of centrepetal force is considered towards both axis of rotation and centre of curvature. Why??
@AkshatNh744 Here’s a simple answer: Why is an ammeter connected in series? An ammeter measures current, which flows through the entire circuit. Connecting it in series ensures all the current passes through the ammeter for accurate measurement. Why is a voltmeter connected in parallel? A voltmeter measures voltage (potential difference) across two points. Connecting it in parallel ensures it measures the exact difference without affecting the circuit. Why does current divide in parallel but voltage divides in series? In parallel circuits, each branch has its own resistance, so current splits based on these resistances. In series circuits, voltage divides across each component proportionally to their resistance. Why does current pass through the body (high resistance) instead of the copper wire (low resistance)? Current doesn’t always follow the shortest path but the path with less resistance combined. If you touch a live wire, your body creates a new circuit to the ground, and the current flows through it because there’s a voltage difference that drives the current through the body, even if the resistance is high.
Sir i am Afeef from class 12 I have a question! Why does current lead against the emf by a phase angle π/2 in capacitive circuit Even though without emf current can't be produced..

Respected sir, I Vivek Singh Jadaun A physics teacher for intermediate classes. Sir, I have a confusion as we know no zeroth order dark fringe exist,but why we are using formula (2n+1)Dλ/d for the position of nth dark fringe. as we have to start the values of n=0,1,2,3.... But zeroth order dark fringe does not exist so why n=0
Sir im a 10th grade student and i have a doubt that as we know that if current passes through a conductor than it also have rasistance which rasist the current if the rasistance rasisting the current than it produce heat by friction so it means that current is decreasing But we also know that in series combination current will stay same but why the current is same in series if it have rasistance which rasist the current and produce heat by friction
Sir my name is Ansh Soni from 9th, as you said in this video that our eyes cannot see the 2nd or more scattering particles, okay no problem but the problem is here that you say in the video that the particle catches the reflection of that particle which is reflecting the light but there are so many particles between them, that is why before coming to our eyes there will be collision with many particles, so it means light should not reach our eyes but light comes to our eyes.
Phele toh focal length ka meaning smjho Focal length of a mirror is the distance from the point of reflection to the point of convergence of all parallel rays yani agr ham bohot saari parallel rays kisi convex ya concave mirror pe Dale toh vo kisi point jise ham focus kehte hain us pr converge hongi mgr agr yahi kaam ham kisi plain mirror ke saath kre toh vohi parallel rays infinity pr meet krengi. That's why focal length bhi infinite hi hogi
But sir according to Rayleigh scattering intensity inversly proportional to wavelength .... So if the light scattered first time and then second time the intensity should be same ...as there is no change in wavelength
Sir you're correct, intensity is inversely proportional to wavelength, but if we look little close, scattering depend on the size of the particle too, if the particle is in the order of first scattered light we can see light is spreading and intensity also will be the same, but if the 2nd particle size is less than the order of scattered light, then it won't scatter at all. then wavelength changes resulting in changing the intensity of the light
@@darsh62 but brother atmosphere has a lots of particles and it is considered homogenous so talking about different sizes in such small distance wont be a wise idea.
But let me tell you rayleigh scattering model is not very accurate scattering follows quantum nature where as rayleigh follows wave nature of light. This you will study while studying black body radiations. What sir said is that the light going in a ray a fraction of it scattered in a direction then out of that again a fraction scattered then out of that again a fraction scattered. Thus the intensity decreases everytime
