Question

calculate the potential difference required
Accross a condnetor of resistance 20
to pass a current of 4A through it - 5​

Answer 1

Answer:

80 volt

Explanation:

We have-:

Resistance = 20omh

Value of current = 4Ampere

We have to find-:

Potential difference = ????

Now-:

As according to ohm's law the required formula is :

=> V=IR

Where,

V is the potential difference accross the circuit,

R is the resistance and

I will be the the current.

So,

On putting all the values we will get

=> V= 4 X 20

=> V = 80 volt

Answer 2

Answer:

4×20

= 80 is the correct answer
