Parallel Resistors and Bulbs
Used to show the difference between resistors in series and in parallel. It is better to use low voltage for parllel circuit 1.5 volts - 3 volts.
|Boards with light bulbs||
Compare the brightness of light when bulbs are connected in series to that when connected in parallel. Show them that series resistance does not have to be on one straight line, just no gap in the circuit. What will happen if one resistor is removed when all are connected in series.
