Explanation:

In an electrical circuit, a load is a component that consumes electrical energy to perform a function (like a lamp, ceiling fan, heat pump, toaster which use electricity for light, motion, heating, or toasting). A light switch is a control device that opens or closes the circuit, not a load as it doesn't consume electrical energy to do work.
