Question

A battery and three lamps are connected as shown

Which of the following statements about the currents at X, Yand 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
