Question on: JAMB Physics - 2024
In voltage measurement, the potentiometer is preferred to voltmeter because it
A
has a wider range
B
consumes negligible current
C
is bulky
D
responds faster than voltmeter
Ask EduPadi AI for a detailed answer
Correct Option: B
The potentiometer is preferred over a voltmeter because it consumes negligible current. At the balance point, no current flows through the circuit being measured, ensuring accurate voltage measurement. A voltmeter draws some current, which may affect accuracy, especially in high-resistance circuits.
