I would say the switch.
with no load, there really is no function. It's just a short circuit, or an open circuit.
I guess the same could be said of the switch, since if it's off there's nothing going on.
But, a working circuit always needs a source, a load, and the wires. A switch is an optional element.
Which of the following parts of a circuit is not actually necessary for the circuit to function?
A. Wire
B. Load
C. Switch
D. Energy source
I put B. The load.
I know you need wires to function since they connect the parts of the circuit.
The switch turns the circuit on.
I wasn't sure between load and energy source but I felt the wires connect to form an energy source .
Is this correct? If not can you please explain? Thank you
