Answer:

H = 0.06 kWh

Step-by-step explanation:

Given that,

Power of an electric lamp, P = 60 W

Voltage, V = 240 V

It is operated for 1 hour

We need to find the heat generated by the lamp. Heat generated is given by :


H=P* t\\\\H=60\ W* 1\ h\\\\H=60\ Wh\\\\H=0.06\ kWh

So, 0.06 kWh of the heat is generated by the lamp.
