Question

do an activity to show the electrical resistance of a conductor​

Answer 1

Answer:

The resistance of a length L (ft) of a conductor can be determined using the specific resistance and the cross-sectional area A (cmil) by using the equation R = r L/A. The specific resistance (r) has units of (ohms•cmil)/ft. The question gives the wire temperature because resistance increases with temperature in metal.

Explanation:

Answer 2

Answer:

Resistance is defined as the property of a conductor to resist the flow of charges through it. The resistance of conductor is numerically given as the ratio of potential difference across its length to the current flowing through it.
