Question

When running on its 11.4 V battery, a laptop computer uses 8.3 W. The computer can run on battery power for 7.5 h before the battery is depleted. Part A What is the current delivered by the battery to the computer

Answer 1

Answer:

The correct answer is "0.73 A".

Explanation:

Given that:

Power,

P = 8.3 W

Voltage,

ΔV = 11.4 V

The current will be:

⇒  $I = \frac{P}{\Delta V}$

On substituting the values, we get

⇒     $=\frac{8.3}{11.4}$

⇒     $=0.73 \ A$
