Question

in a power - side switched circuit, when the circuit is off, voltage is present to which point?
a) the switch
b) the load
c) the battery
d) the fuse

Explanation:

In a power - side switched circuit, when the circuit is off, the power (voltage) is still supplied up to the switch. The switch is the component that interrupts the flow of current to the load. The battery is the source of voltage, but the question is about where the voltage is present when the circuit is off (in terms of the components in the circuit path). The fuse is also in the power supply path but the key point is that in a power - side switched circuit, the voltage is present at the switch when the circuit is off as it is on the power - side (source side) of the switch.

Answer:

A. The switch
