| Challenge 1 | | Make a simple series circuit with a cell, a lamp and a switch so that the lamp comes on when you close the switch.
This is like a torch circuit. |
| Challenge 2 | | What effect does the number of cells have? Adding cells to a battery and making the lamp brighter. |
| Challenge 3 | | Measure current in a simple series circuit. Find out if it gets used up. |
| Challenge 4 | | Find out what happens to the current if you change the number of cells in a battery. |
| Challenge 5 | | What effect does the number of lamps (in series) have? Try adding lamps in series and see what happens to the brightness. |
| Challenge 6 | | Try measuring the current in a series circuit with two lamps. How does it compare with the current in a circuit with a single lamp? |
| Challenge 7 | | Make a parallel circuit with a cell and two lamps. Try disconnecting one of the lamps. What happens to the brightness of the other one? |
| Challenge 8 | | What is the current at various points in a parallel circuit? |
| Challenge 9 | | Build some challenging circuits. |
| Challenge 10 | | Build some more challenging circuits with 4 cells. |
