Question

A battery with internal resistance r is connected to a load resistance R. If R is increased, does the terminal voltage of the battery increase, decrease, or stay the same? Explain.

Short answer

The battery's terminal voltage will rise as the load resistance rises.

Step-by-step solution

Step 1. Given information

Internal resistance $=r$

External resistance$=R$

Step 2. Find the variation in terminal voltage when load resistance increases

The terminal voltage will grow as load resistance $R$is raised in contrast to load resistance $r$.

This is due to the fact that voltage will be distributed in proportion to the resistance ratio.

As the load resistance increases, the battery's terminal voltage rises.
