Question

What will be the current, if the potiental difference is kept constant and the resistance of the circuit is made four times

Answer 1

Explanation:

current will be increased by 1/4 times

Answer 2

Answer:

Explanation:

V = IR

I = V/R

for eg : V = 100, R = 5

I = 100/5 = 20

Now V taken as const, R = 5 *4 = 20

then I = 100/20 = 5

current is reduced 4 times
