Read each question carefully and answer to the best of your ability. Show your work for calculations.
1. What happens to the total resistance in a series circuit when you add more resistors?
It decreases
It increases
It stays the same
It becomes zero
2. In a parallel circuit, if one light bulb burns out, what happens to the other bulbs?
They all go out
They get brighter
They stay lit
They dim
3. In a series circuit, resistors are connected one after another, forming a single for current.
4. In a parallel circuit, resistors are connected across each other, providing multiple for current.
5. Explain the main difference between a series circuit and a parallel circuit in terms of how current flows.
6. Look at the circuit diagram below. Is it a series or parallel circuit? Explain your reasoning.
7. Adding more resistors in a parallel circuit will decrease the total equivalent resistance.
True
False
