Question

An operating 100-watt lamp is connected to a 120- volt outlet. What is the total electrical energy used by the amp in 60 seconds?

Answer 1

The energy is `=6kJ`

Explanation:

The electrical energy is

`E=UIt=Pt`

The power is `P=100W`

The time is `t=60s`

The electrical energy is

`E=100*60=6000J=6kJ`
