Question

derieve the equation P=V^2/R rest chat​

Answer 1

Explanation:

P=VI........(1)

By ohms law

V=IR

I=V/R

putting value of I in eq 1

P=V*V/R

P=V^2/R

mark as brainliest if i deserve it

Answer 2

hello

Power(P)=Potential difference (U)× Current (l)

so

Now by the ohm's law

l=V/R

On substituting value of current in the equation

P=Vl

We get

P=V×V/R

P=V ^2/R

Hope it helps.
