JEE MainPhysicsCurrent ElectricityMCQ+4 / −1
In a Wheatstone bridge(see fig.), Resistances P and Q are approximately equal. When R = 400 Ω\OmegaΩ, the bridge is balanced. On interchanging P and Q, the value of R, for balance, is 405 Ω\OmegaΩ. The value of X is close to : JEE Main 2019 (Online) 11th January Morning Slot Physics - Current Electricity Question 269 English
