Hey......I am replying on my own comment😆😆😆

[@thaminauddin3600]

Lol

[@silentstormstudio4782]

It's really confusing in another tutorial the negative terminal of the transducer is connected to positive of ammeter

[@felixolsson8769]

If you connect your power supply the other way around, the circuit will still work. A current will still flow (just the other way).
The only difference would be that ammeter and voltmeter would show negative values if we reversed the terminals of the power supply.

[@edwintumwebaze6617]

Thank you very much. This video has cleared all the contradictions.

[@MsJovi102]

Can you list some precautions and possible sources of error for an experiment such as this? Thank you.

[@felixolsson8769]

MsJovi102 Voltage is low, so no real hazards. Just take care as input to powerpack is from mains. Resistor can get hot for big currents so take care when handling. Sources of error: calibration of meters (zero error), reading scales on meters, minor fluctuations in readings during each trial; if you are going to find R of resistor using the graph gradient, then the resistance of connecting wires is another source of error to consider.

[@periwinkle2881]

components may become heated due to the current flowing through the circuit, causing the effective resistance to increase which affects the p.d and current reading.

[@soumyajitdas6598]

I have a doubt .Suppose I connect the power supply directly to the ammeter .Does the ammeter give any value?Does this value is more than the ammeter reading when we out a resistor in the circuit.

[@felixolsson8769]

Ammeter has very small (ideally zero) resistance. Thus, current will become very large if just the ammeter is connected (a short circuit). Most powerpacks protect against this by having a circuit breaker, which automatically turns powerpack off if current gets too big. Remember: current is voltage/resistance, so if resistance gets very small, current gets VERY big.

[@frosty-tp6yn]

May God bless your soul.

[@shivaprasadg8622]

Thanks for perfect explanation!!

[@yienannchoo82]

May I ask how do we know which wire to use to connect the terminals? And how to know which terminal connect to which?

[@vg6761]

Its colour coordinated

[@JaleewNyamugumura-cn4tz]

Well explained...thank you

[@JohnGimei]

Thanks l got it all

[@mahantheshanchatnnalli4782]

If I will connect ammeter after resistor (near positive terminal) what will happen. Is current varies?

[@sapnarahim9311]

U made it easy sr thanks

[@divineart1089]

Can you add a load like the knob type resistor box to this circuit

[@emmanueliwuchukwu7342]

This is wonderful

[@AnkitaSingh-un3sj]

Can we make the circuit without using resistor or rheostat?

[@mauricksatyam1020]

Great help.Thank you so much

keep it up

[@abdulhamidbani2712]

Very clear , thanks

[@umarali9523]

easy method thank you for

[@rahelhemafrexk3635]

is voltmeter reads from zero or is just a source of error (+ error)

[@sohelnurani2012]

Thank you sir👍👍👍

[@healthyylaughs]

What is the name of the nosil you added to connect wire to key

[@felixolsson8769]

Do you mean the crocodile clip? Some call them alligator clips :)

[@kielsteevebugtay2581]

thank you!!!!!!!

[@rodriannapaleo-hq8zy]

Thank you❤❤❤

[@acapali7763]

how many ohm did u use for resistor ?

[@felixolsson8769]

Cant remember, but you should be able to work it our from the voltage and current😁

[@rithishnalla8324]

Can u make good process to write in exam

[@azhadkhan2945]

Rheostat kahan par hai

[@karanveersingh1139]

Pls tell why ammeter is connected negative to negative and positive to positive?

[@felixolsson8769]

They are just made that way - it's convention. If you hook it up the other way you will get a negative reading.

[@hpspspspsps5798]

can you make a video on the kinds of resistors?

[@ronnyfoodie5557]

Carbon Composition Resistor.
Thermistor.
Wire Wound Resistor.
Metal Film Resistor.
Carbon Film Resistor.
Variable Resistor.
Varistor
Light Dependent Resistor.

[@dheerajnaik2680]

Simple and good one.

[@CharishmaCNair]

Thank you so much!!

[@shortvideomusicgamingprodu326]

super

[@robertgeorge6322]

Among d 2 small machines which one is ammeter and voltmeter

[@felixolsson8769]

Robert George The one with A on it is ammeter, V is voltmeter. It is kinda small, but you should be able to see it.

[@jayasingha7102]

Haw to mark Ampiyr metor resisror....

[@earningguru123]

good idea

[@ephraimmoyo6832]

Well explained.

[@purnimaroy818]

[@chandanrathore747]

Need For exam can you explain it with whole process

[@fredlee9362]

Out of all the useless crap i learned in school circuits is by far the top of my list

[@sushantaroy5091]

Good but where is the rheostat

[@sintusahani6931]

Name of Connective wire

[@MarkisCouch_1WhatJustHappened]

Informative!

[@chesleygirlviolinmusic5629]

How many ohms is your resistor?

[@felixolsson8769]

Arjel Onde Hi. It was a 10 ohm resistor. You can see the whole experiment carried out here: th-cam.com/video/hxYn74Yhkpk/w-d-xo.html. The resistance is the voltage lost across resistor divided by the current through the resistor.

[@chesleygirlviolinmusic5629]

Felix Olsson thanks for the reply...I really appreciate it... I have no practical knowledge about electricity and all those lab experiments... Every now and then i am watching tutorials in youtube... But theory wise, i can explain and discuss all of it.... nice video by the way...

[@Focuspls-xk8sj]

After 30 min.... I have to give my practical 😂😂

[@skmaan2963]

Sir how to connect rheostat in this circuit

[@felixolsson8769]

Hi, if you have a constant voltage supply, and want to use a rheostat to vary the voltage across the resistor/bulb, then connect your resistor/bulb as in this diagram - bit.ly/2M6ZzU9 - and put your ammeter in series with bulb/resistor, and voltmeter in parallel with the bulb/resistor. You can then use the rheostat to vary the bulb voltage from 0 to max.

[@mummyreturns6188]

No rheostat

[@felixolsson8769]

shah j No. I am testing the effect of supply voltage on current so I am not changing resistance - so I am not using a rheostat.

[@mummyreturns6188]

Felix Olsson ok but can you make rheostat video circuit with rheostat plz😫😫😫

[@shrutim7775]

Thanks

[@Trikin.24]

Where's rhrostat
