Question

1. How does changing the voltage in a circuit affect the current in the circuit? 2. What is the impact of adding more light bulbs in series? 3. In the series circuit, is the current constant throughout the circuit, or does it vary?

Answer 1

1. Changing voltage increases the current.
2. Adding more lightbulbs increase the resistance and the light bulbs become dimmer as the current has to be shared.
3. Yes its constant.
