Question

A  12 Ω  resistor rated at  20W  is connected directly across a  24V  supply. The  power dissipated  will be:

Answer

close to the resistor’s maximum power rating but still within operational range

Answer

minimal and there will be negligible heat generated

Answer

around half of the resistor’s power rating with capacity for more current to flow

Answer

beyond the resistor’s power rating and the resistor will be damaged
