Question

Four resistors of resistance 20Ω, 20Ω, 20Ω and 30 Ω form a Wheatstone’s network. What shunt is required across 30Ω resistor to balance the bridge? a) 10Ω b) 30Ω c) 20Ω d) 60Ω​

Answer 1

Answer:

the answer is 0

Explanation:

I try my best but I think it's correct

Answer 2

let Rs in the shunt resistance

Rs = 60ohm
