When 2 Ω, 4 Ω, and 6 Ω resistors are connected in parallel, their resultant equivalent resistance will be _.
Correct answer: C. 12/11 Ω
- A. 12 Ω
- B. 11/12 Ω
- C. 12/11 Ω
- D. The data is insufficient
Explanation
As more and more resistors are added in parallel to a circuit, the equivalent resistance of the circuit decreases and the total current of the circuit increases. Adding more resistors in parallel is equivalent to providing more branches through which charge can flow. ½ + ⅙ + ¼ = 12/11.

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.
