An electric iron of 500 w power is used for 10 hours. The electrical energy consumed is ___________________ kWh 

Given,

Power, P = 500 W

Time, T = 10 h

Energy, E = ?

Solution-

We know that, 

$E=P\times \frac{t}{1000}$

where E = energy in kilowatt-hours(kWh), P = power in Watts (W), t = time in hours (h)

Substituting the given values in the formula, we get-

$E=500\times \frac{10}{1000}$

$E=5kWh$

Thus, the electrical energy consumed by 500W electric iron in 10hour is 5kWh.
