Question

If P is the power of an electric circuit such that R is its resistance, I is the current flowing through it and V is potential difference at the ends of electric circuit then:

पर्याय

• P = I × V

• P = I²R

• $$P = \frac{V^2}{R}$$

• all of these

Answer 1

All of these

Explanation:

The power formulas are $$P = IV$$, $$P = I^2R$$ and $$P = \frac{V^2}{R}$$. Each of the first three options is a correct expression for electric power.
