The electrical energy consumed by an electric heater in a duration of 3 h is 0.6 K W h. What is the power consumed by the heater?

Explanation

The duration for which an electric heater used t = 3 h.
Energy consumed (E)=0.6 kW h.
`:.` Power of the heater (P) = ?
We know that power (P) = `("energy consumed")/("time taken")`
`rArr =P = (0.6 k W h )/(3 h)=0.2 k W = 0.2 xx 1000 W`
` = 200 W`
`:.` Power of the heater (P) = 200 W.
