Question 1.
What happens to the total voltage when cells are connected in series?
Show hintHide hint
Think about the contribution of each cell.
Question 2.
What unit is resistance measured in?
Show hintHide hint
Remember the symbol for the unit of resistance.
3Question 3.
What happens to the voltage in a series circuit?
- It increases
- It decreases
- It stays the same
Show hintHide hint
Consider the additive nature of series connections.
4Question 4.
In a parallel circuit, the total current is:
- The sum of individual currents
- The same as one branch
- Less than individual currents
Show hintHide hint
Think of flow splitting across multiple paths.
Question 5.
You have two resistors, 5Ω and 10Ω, connected in series with a 12V battery. What is the total current flowing through the circuit?
Show hintHide hint
Don't forget Ohm's law!
Question 6.
If you connect three resistors in parallel, 2Ω, 3Ω, and 6Ω, to a 12V battery, find the equivalent resistance and the total current flowing.
