Question

A battery and three lamps are connected as shown:

Which of the following statements about the currents at X, Y and Z is correct?
(a) The current at Z is greater than that at Y.
(b) The current at Y is greater than that at Z.
(c) The current at X equals the current at Y.
(d) The current at X equals the current at Z.

Solution

(b) The current at Y is greater than that at Z.
This is so because Y alone will offer less resistance.
