Conductance is
Correct answer: A. Reciprocal of resistance
- A. Reciprocal of resistance
- B. Measured in ohm
- C. Another name of resistance
- D. All of the above
Explanation
Conductance is defined as the measure of how easily electric current flows through a material, and it is calculated as the reciprocal of resistance. The correct answer is the first option: "Reciprocal of resistance," because it accurately describes conductance. The second option is incorrect because conductance is not measured in ohms; it is measured in siemens (or mho). The third option is incorrect as conductance is not another name for resistance; they are distinct properties that are inversely related. The final option is also incorrect, as it incorrectly combines true and false statements.

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.
