A string of decorative lamps is connected to a power supply. What is a disadvantage of connecting these lamps in a series circuit rather than a parallel circuit?
The total resistance of the circuit is reduced, which can cause overheating.
If one lamp breaks, all other lamps in the circuit will stop working.
Each lamp in the circuit receives the full voltage of the power supply.
Multiple switches are required to turn all the lamps on at the same time.
