Question

A color TV uses 120 W of power. How much energy does the TV use in 1
hour?

Answer 1

The quantity of energy used by the color TV is equal to 432 Kilojoules.

Given the following data:

• Time = 1 hour

• Power = 120 watt

Conversion:

1 hour = 60 minutes = $60 \times 60 = 3600$ seconds.

To determine the quantity of energy used by the color TV:

Mathematically, energy with respect to power and time is given by the formula:

$Energy = power \times time$

Substituting the given parameters into the formula, we have;

$Energy = 120 \times 3600$

Energy = 432,000 Joules

Note: 1000 Joules = 1 Kilojoules.

Energy = 432 Kilojoules.
