Question

During lab, you observed that the voltage across a real battery changes when current flows through it. What happens to the voltage across the battery when the load of the battery changes. More than one answer may be correct. Choose all correct answers.

The voltage across the battery increases slightly when the current increases

The voltage across the battery decreases slightly when the current decreases

The voltage across the battery decreases slightly when the current increases

The voltage across the battery increases slightly when the current decreases.

Explanation / Answer

Answers C&D

Internal resistence of a battery causes a voltage drop as currnt flows.

Therefore, when current through battery increased, voltage drop due to internal resistance increases and when current decreases, voltage drop decreases
