Physics Question on Current electricity
The potentiometer is best for measuring voltage,as:
A
It has a sensitive galvanometer
B
It has wire of high resistance
C
It measures p.d. like in closed circuit
D
It measures p.d. like in open circuit
Answer
It measures p.d. like in open circuit
Explanation
Solution
The potentiometer is best for measuring voltage because it allows for precise and accurate measurement of electrical potential difference (voltage) by comparing it to a known reference voltage.
So, the correct option is (D): It measures p.d. like in open circuit.
