How much electricity does a laptop use in 24 hours

Asked by admin @ 26/11/2021 in Mathematics viewed by 329 People

A laptop computer consumes about 20 watts of electricity per hour when operating. At 10 cents per kilowatt-hour, how much does a laptop cost to operate for 5 hours?

Answered by admin @ 26/11/2021

The cost of the energy consumed by the laptop for the 5 hours period is 5 cents.

Given:

rate of energy consumption of the laptop, R = 20 Watts per hour

time of operation of the laptop, t = 5 hours

cost of energy consumption, c = 10 cent per kWh

To find:

the cost of the energy consumed by the laptop for the 5 hours period

The energy consumed by the laptop in kWh is calculated as;

$Energy = Power \times time \\\\Energy = (\frac{20 \ W}{hr} \times 5 \ hr) \times 5\ hr\\\\Energy = (100 \ W) \times ( 5 \ hr)\\\\Energy = (0.1 \ kW) \times (5 \ hr)\\\\Energy = 0.5 \ kWh$

The cost of consuming 0.5 kWh is calculated as;

$Cost = energy \ rate \ \times \ energy \ consumed \\\\Cost= \frac{10 \ cent}{kWh} \times 0.5 \ kWh\\\\Cost = 5 \ cents$

Thus, the cost of the energy consumed by the laptop for the 5 hours period is 5 cents.
