A student is planning a lighting circuit for a dolls’ house. He arranges two different circuits. In each circuit, there is a $12\text{ V}$ power supply and three identical lamps. Each lamp is intended to shine at normal brightness when it is connected on its own to a $12\text{ V}$ supply. Which statement is correct?
- AIn circuit 1, each of the lamps is at normal brightness.
- BIn circuit 1, if one lamp fails, the other lamps remain lit.
- CIn circuit 2, if one lamp fails, the other lamps remain lit.
- DIn circuit 2, the current from the power supply is less than in circuit 1.
