When a Wheatstone bridge is in a balanced condition, the center voltmeter in the bridge will read_____________?
Correct answer: C. zero volts
- A. twice the source voltage
- B. half the source voltage
- C. zero volts
- D. the same as the source voltage
Explanation
A balanced Wheatstone bridge has equal potential at the two midpoint nodes, so there is no voltage across the center voltmeter. The meter therefore reads zero volts.
