Answer 3

40 watt bulb for 1 hour uses .040 kwh, a kwh = a kilowatt hour = watts multiplied by time / 1000.

a kwh costs about $0.12 or 12 cents

So at 40 watt bulb for 1 hour costs about $0.0005
which is next to nothing.

A TV is about 150 watts so in one hour uses 0.150 kwh which times $0.12 is $ 0.005 which is 1/2 cent

A computer is about the same as TV for power so the cost is about the same maybe slightly higher.
