Question

A fresh D cell battery has a terminal voltage of 1.6 V and can supply up to 8.0 A into a short for a very short time. What is the internal resistance of the battery?

Answer 1

Answer:

2 ohms

Explanation:

The terminal voltage is 1.6 volts

The current is 8

Therefore the internal resistance of the battery can be calculated as follows

R= V/I

= 1.6/8

= 2 ohms

Therefore the internal resistance of the battery is 2 ohms
