Question
Figure shows the circuit diagram of a Wheatstone bridge with P=4kΩ, Q=10kΩ, R=2kΩ, S=13Ω. This Wheatstone bridge is_____________a.Balancedb.Cannot be determined unless we know the applied voltagec.Not balanced
Solution
The Wheatstone bridge is said to be balanced when the ratio of resistances P/Q equals the ratio of resistances R/S.
In this case, P/Q = 4kΩ / 10kΩ = 0.4 and R/S = 2kΩ / 13Ω = 153.85.
Since 0.4 is not equal to 153.85, the Wheatstone bridge is not balanced.
So, the answer is c. Not balanced.
