What would happen to the total resistance of a circuit if you added a component with very low resistance in parallel to the circuit?
The total resistance would increase substantially
The total resistance would decrease substantially
The total resistance would remain the same
The total resistance would become very high
הֶסבֵּר
Adding any resistance in parallel will always decrease the total resistance.
