The reciprocal of resistance is:
Correct answer: C. Conductance
- A. I
- B. Resistivity
- C. Conductance
- D. Zero
Explanation
Resistance (R) is a measure of how much a material opposes the flow of electric current, and its unit is ohms (Ω). The reciprocal of resistance is conductance (G), which is given by: G=1/R Conductance is measured in siemens (S). It represents how easily electric current can pass through a material.

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.
