Question

If current flowing through a device is a doubled how Resistance, Potential Difference and power of devices get affected

Answer 1

Answer:

Explanation:

If current flowing through a device is a doubled how Resistance, Potential Difference and power of devices get affected

current flowing through a device is dependent upon Resistance & Potential difference .

For a given circuit resistance does not change until additional load is applied or load is removed

I ∝ V

I = V/R  ( R is constant)

Current will be doubled if V is doubled

Hence Potential Difference is doubled

Power = V²/R   so power is increased by 2² = 4 times

We can also increase current by Increasing Load / Decreasing Resistance

I = V/R

Then Resistance is Halved

Potential difference Remains same

Power = V²/R  & R is halved so power become 2 times

Answer 2

Answer:

it is halved
