Combination of Resistors

The resistors...

Question

The resistors $R_{1}, R_{2}, R_{3} a n d R_{4}$ in the figure given below are all equal in value.
What would you expect the voltmeters A, B and C to read assuming that the connecting wires in the circuit have negligible resistance?

Solution

Since, the circuit has four resistances of same value.

Therefore, the voltage drop across each resistor will be same.

12/4 = 3 v each.

Across A = 3 v

Across B = 3 v

Across C = 3+3 = 6 v
