Question
Wheatstone bridge with P=250Ω, Q=100Ω, R=1500Ω, S=600Ω. This Wheatstone bridge is_____________
Solution
The Wheatstone bridge is a device used to measure unknown electrical resistance. It is based on the principle of balance, which states that in a balanced bridge, the ratio of the resistances in one branch (P and Q) is equal to the ratio of the resistances in the other branch (R and S).
To determine if the given Wheatstone bridge is balanced or not, we can use the formula:
P/Q = R/S
Substituting the given values:
250/100 = 1500/600
2.5 = 2.5
Since the ratios are equal, the Wheatstone bridge is balanced.
