In the circuit diagram, two identical lamps are connected in parallel across a cell. Three ammeters, X, Y and Z, are also included in the circuit, as shown. Which statement about the current in X is correct?
- AIt is equal to the current in Y and to the current in Z.
- BIt is less than either the current in Y or the current in Z.
- CIt is equal to the sum of the current in Y and the current in Z.
- DIt is equal to the difference between the current in Y and the current in Z.
