The question above has multiple choices;
a) A longer conductor will have more resistance.
b) A large diameter wire will have less resistance.
c) Resistance determines the amount of current that can flow in a circuit
d) All of the above?
The answer is (D) All the above.
You can compare Resistance in electrical circuit to a small water pipe resisting the flow of water. Thus, Resistance is an obstruction to electrical flow. The amount of current flow is inversely proportional to the resistance in the circuit. This means that the more the resistance, the less the current flow. By default, the longer the wire, the larger its diameter must be.
