NAND gate using TRANSISTORS | video in HINDI

- In this Physics (electronics) video in Hindi for class 12 we explained the construction of NAND gate using transistors and compared this circuit with the circuit diagram of AND gate. To create this circuit we need to have two transistors connected in series (emitter of the first one is connected to the collector of the other one) and two input signals are feed in the bases of those transistors. NAND gate works opposite of the AND gate. It gives signal in the output, when at least one the inputs have no signal.
In other videos we discussed how to construct other logic gates using transistors and in one of the upcoming videos we will discuss how to construct NAND gate using p-n junction diode.

Sir, according to your NAND gate circuit diagram, when both the input are 1, the path toward ground and the path toward y both have 0 resistance. So half of the current would still be flowing into y. I think the resistance should be on the wire connecting y rather than the wire connecting 5v. Correct me if I'm wrong. Thank you❤️✨
Thank you sir, a very simple explanation of all Gates
Sir bohot badiya explanation. Maza aagaya
In last case when both input signal 1 and 1 then how the output zero kindly explained..
Thank you, sir. 😊

Sir agar aapke jese teacher ho to hum Einstein ban jayenge
VERY INFORMATIVE
Sir NAND gate par 5k ka resistance lagaw to 'y' pe to current nahi aiye ga... Shif voltage hi ayega... Too current bina koe equipment kese chalega???

nice video
Hum ne ek hi npn transistor ke sath resistor connect kiya to same situation rahega
Sir aap se request thi ki aap 2017-18 ke nye topic ko bhi discuss karnge....
nice video but please upload video semiconductor and communication system.
Hello Pankaj Kumar !
Yes ! Stay with us.
I shall create more.
Sir practical circuit and theory don't ek sath dikaye
thankyou sir kya apke sabhi video class12 ke hai
Nahi.
Class 11 aur B.Sc. ke bhi videos hai.
Sir in NCERT solved example 4.11 on page 159-160 of class 12, it is given that
[(Example 4.11) A 100 turn closely wound circular coil of radius 10 cm carries a current of 3.2 A.
(a) What is the field at the center of the coil?
(b) What is the magnetic moment of this coil?
The coil is placed in a vertical plane and is free to rotate about a horizontal axis which coincides with its diameter. A uniform magnetic field of 2T in the horizontal direction exists such that initially the axis of the coil is in the direction of the field. The coil rotates through an angle of 90º under the influence of the magnetic field.
(c) What are the magnitudes of the torques on the coil in the initial and final position?
(d) What is the angular speed acquired by the coil when it has rotated by 90º? The moment of inertia of the coil is 0.1 kg m^2.
Sol. (c) τ = m × B [from Eq. (4.29)]
= m B sinθ
Initially, θ = 0. Thus, initial torque τi = 0. Finally, θ = π/2 (or 90º). Thus, final torque τf = m B = 10 × 2 = 20 N m.]
{I have only pasted the solution of part (c)}
My question is that if initial torque is zero, how can the coil rotate due to magnetic field in the first place?
I think that it is possible that the question and/or answer is wrong, but if I am wrong and question and/or answer is correct. Then please let me know and please provide the diagram of the situation if it is correct.
What
Very superficial explanation
Not proper explained
I shall try again.
yes
at last i did understood last case of nand gate
@@edupoint.physics bilkul is main toh AND ko hee repeat kr gaye sir..
