MCQ
Pick out the application of potentiometer from the following.
- AIt measures current.
- BIt measures internal resistance.
- CIt measures external resistance.
- DIt is used to compare two currents.
✓
Answer
- It measures internal resistance.
Explanation:
Potentiometer is an electric instrument used to measure internal resistance, electromotive force (emf), and it is also used for comparing the emfs of different cells. Potentiometer can be used as a variable resistor as well.
