If a resistor having resistance 'R' is cut into three equal parts, then the equivalent of a parallel combination is:
Correct answer: C. R/9
- A. 6/R
- B. 3/R
- C. R/9
- D. R/3
Explanation
3/R: This option suggests that the equivalent resistance of the parallel combination of the three equal parts is 3/R. This is the correct answer.

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.
