A portable television using a 12 volt, 3 Ah rechargeable battery can operate for a period of about 6 hours. What is the average current drawn in amperes during this period

0.5 A

Explanation:

Current: This is defined as the rate flow of electric charge round a circuit,

The S. I unit of current is Ampere (A). Mathematically,

Current (I) = C/t

I = C/t ... Equation 1

Where C = capacity of the battery, t = time

Given: C = 3 Ah, t = 6 hours.

Substitute into equation 1

I = 3/6

I = 1/2

I = 0.5 A.

Hence the average current drawn = 0.5 A
