Question
As per the figure below and identify which of the two circuits shown will cause the light bulb to light:Pick an answer:
- (A)
- (B)
- None
- Both
- The drawing is not clear enough to decide
Answer:
The circuit in diagram A, there is no potential difference in the closed circuit.Whereas the circuit in diagram B will allow the light bulb to light because of the existence of a closed circuit.
Hence, having the switch open or closed will not interfer since it is in parallel with another conductor.
