Three 6 Ω are connected as shown in the diagram What is the resistance between points 'A' and 'B'
Correct answer: D. 2 Ω V
- A. 6 Ω
- B. 16 Ω
- C. 4 Ω
- D. 2 Ω V
Explanation
If looked into closely, these resistors are actually parallel to each other. The total resistance is equal to: 1/R-1/R1+1/R2+1/R3 1/R=1/6+1/6+1/6=3/6 1/R=2 R=2 ohms. As it is a numerical, it can have only one possible 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.
