Question

WHY SOURCE RESISTANCE NOT AFFECT READING IN POTENTIOMETER

Answer 1

Explanation:

Number of Connections Three Terminals Two Terminals

Number of Turns Single and Multi-turn Single-turn Only

Connection Type Connected Parallel with a Voltage Source Connected in Series with the Load

Quantity Controlled Controls Voltage Controls Current

Answer 2

Explanation:

Sensitivity of potentiometer can be increasedby. Sensitivity of potentiometer can be increased by increasing the length of thepotentiometer wire and by reducing the current in the circuit by using a rheostat. Both the methods help in decreasing the potential gradient, and thereby increasing the resistivity.
