- 17. Multiple Choice
2 answers:
Open circuit or closed circuit?
Will the light bulb light up?
Open circuit
Closed circuit
Light bulb WILL light up
Light bulb WILL NOT light up
- 18. Multiple Choice
In a closed circuit, how does battery voltage affect current?
As voltage increases, current increases.
As voltage increases, current decreases.
Voltage has no affect on current.
If voltage exceeds current, a short circuit circuit will develop.
- 19. Multiple Choice
