Question 1.
What happens to current in a series circuit?
Show hintHide hint
Think about how the flow of electricity works.
Question 2.
How do you calculate the total resistance in a series circuit?
Show hintHide hint
Look for the formula using addition.
3Question 3.
In a series circuit, the total current is:
- The sum of individual branch currents
- The same throughout all components
- Variable depending on voltage
Show hintHide hint
Consider how electricity flows in a single pathway.
4Question 4.
In a parallel circuit, the voltage across each branch is:
- Different
- The same
- Not applicable
Show hintHide hint
Think about how power is supplied to multiple devices.
Question 5.
Design a simple electrical circuit project that uses both series and parallel components. Explain the advantages of your design choices.
Show hintHide hint
Consider how to balance the electrical load.
Question 6.
Analyze the impact of adding additional resistors in series versus in parallel on the overall resistance and current flow of the circuit.
Show hintHide hint
Use Ohm's Law to back your analysis.
