Question

If the electricity in an area cost $.11 per KWH kilowatt times hour, how much does it cost to run a 60 W lightbulb at 120 V continuously for 30 days show your work

Expert Solution

Step 1

Given data

The cost of electricity in an area is: C = $ 0.11/ kWh

The power consumed by the light bulb is: P = 60 W

The potential difference of the bulb is: V = 120 V

The time of working of the bulb is: t = 30 days

The expression for the total cost to run the bulb is given as:

$C_{t o t a l} = C P t$

Substitute the value in the above equation.

$C_{t o t a l} = $ 0.11 \times \frac{1}{kWh} \times 60 W \times 30 days$
