Show hintHide hint
Think about how individual voltages combine.
Question 2.
What remains constant in a series connection?
Show hintHide hint
Consider the flow through each cell.
3Question 3.
What is the result of connecting cells in series?
- Increased voltage
- Increased resistance
- Increased current
Show hintHide hint
Think about how voltage adds up.
4Question 4.

- True
- False
Show hintHide hint
Consider how the connections affect voltage.
Question 5.
If a battery bank consists of three batteries each rated at 12V and connected in series, what is the total voltage available from this configuration?
Show hintHide hint
Add the voltages of each battery connected in series.
Question 6.
Consider a situation where a 10Ω and a 5Ω resistor are connected in parallel. Calculate the total resistance and explain why the total resistance is less than the smallest individual resistance.
