Question

In a Wheatstone bridge, the bridge is balanced when the ratio of the resistances in the four arms satisfies [H] [width=0.5\linewidth]{108.png}

• A. $P/Q = R/S$
• B. $P/R = S/Q$
• C. $PS = QR$
• D. $P+Q = R+S$

Hint:

Remember that in a balanced Wheatstone bridge, the product of the resistances on one pair of opposite arms is equal to the product of the resistances on the other pair.

Answer 1
