The resistors R_{1}, R_{2}, R_{3} and R_{4} in the figure given below are all equal in value.

What would you expect the voltmeter A, B and C to read assuming that the connecting wires in the circuit have negligible resistance?

#### Solution

The p.d across all the resistors *R*_{1}, *R*_{2}, *R*_{3} and *R*_{4} is 12 V.

Since all the resistors are of the same value, the p.d at exactly half of the combination, i.e. the voltage shown by the voltmeter *C* will be 6 V. Similarly, the p.d. shown by the voltmeters *A* and *B* is one-fourth the p.d. across all the resistors. Therefore, *A* and *B* will have a reading of 3 V.
