An electric iron consumes energy at a rate of 880 W when the heating is at the maximum rate and the voltage applied is 220 V. What will be the resistance of electric iron?

The resistance of electric iron is

55 Ω

.
Given that,
power,

P = 880 W

, and
voltage,

V = 220 V

We have to calculate resistance

R

.
We know that,

\Rightarrow P = \frac{V^{2}}{R}

By putting given values on the above equation,

\Rightarrow

880 = \frac{220 \times 220}{R}

\Rightarrow R = 55 Ω .
