Question
Identify the correct circuit diagram
Hint:
- Same polarity and the direction of current is from higher to lower potential.
The correct answer is:
- Cells in a battery should always be connected in the same polarity(+ - + -).
- Current flows from the higher potential to the lower potential which means it leaves the battery form it's higher potential end and enters in it through its lower potential end..
- So, the correct option is b.
- If the cells in a battery are connected with opposite polarity(-++- or +--+) then the voltages try to cancel each other.
