The total resistance of wire is inversely proportional to
Correct answer: B. area
- A. length
- B. area
- C. temperature
- D. time
Explanation
he resistance of a wire is inversely proportional to its cross-sectional area. This means that as the area of the wire increases, the resistance decreases. This relationship is described by the formula R = ρ(L/A), where R is the resistance, ρ is the resistivity of the material, L is the length of the wire, and A is the cross-sectional area of the wire. As A increases, R decreases, so it is correct to say that resistance is inversely proportional to area.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
