Question
Q4/ In the following figure, the first resistance (R1 = 202) and the second
resistance (R2 = 1002), calculate:
1- The value of the resistance (R4) when the bridge is in equilibrium
(V1 = V2) and the value of the variable resistance (R 3 = 502).
2- The value of the variable resistance(R3)when it is(V1 = 3V2).
