Question

Four resistances of 10Ω, 60Ω, 100Ω, and 200Ω respectively taken in order are used to form a Wheatstone’s bridge. A 15V battery is connected to the ends of a 200Ω resistance, the current through it will be?

• A. \( 7.5 \times 10^{-5} \) A
• B. \( 7.5 \times 10^{-4} \) A
• C. \( 7.5 \times 10^{-3} \) A
• D. \( 7.5 \times 10^{-2} \) A

Hint:

In a Wheatstone bridge, the current depends on the ratios of the resistances.

Answer 1

The Correct Option is D

In a Wheatstone bridge, the current through the resistance is determined by the total resistance in the circuit. Using Ohm's law, the current through the given 200Ω resistance can be found.
