Question 5.
If two resistors of 4Ω and 8Ω are in series and this combination is in parallel with a 2Ω resistor, what is the total resistance?
Show hintHide hint
Solve the series combination first, then apply the parallel formula.
Question 6.
An electrical circuit has 3 sets of batteries: two sets of 1.5V batteries in series, combined in parallel with a higher voltage set of 3V. Calculate the overall voltage.
Show hintHide hint
Remember that in a parallel configuration, voltage remains constant.
