Hi Everyone,
I have a general question.
I can calculate series and parallel circuits ok, with one power source, such as a battery but how do I work out resistance values when there are two power sources (in a DC circuit)?
For example, two 9v batterys wired in series, with 1 X 5 ohm and 1 X 10 ohm resistor and a 12v lamp - all in series.
Regards,
Luke
