The voltage of a power supply drops to 0 V when connected to a lamp circuit.What is a possible problem?

Question

Quizplus · Accepted Answer

If the voltage drops to 0 V when connected to a lamp circuit, it means that the power supply is unable to deliver any current to the lamp. This could be due to the lamp being shorted, which provides a path of low resistance to the current, causing it to bypass the lamp and flow through the short circuit instead. Alternatively, the lamp may require more current than the power supply can deliver, which causes the voltage to drop to 0 V as the supply cannot provide the amount of current required. Therefore, both options B and C are possible problems that could cause a power supply to drop to 0 V when connected to a lamp circuit.
