Across
- 3. used to measure the current
- 4. this will make the current smaller
- 6. can turn the circuit off and on
- 7. a light dependent resistor
- 11. used to measure the voltage
- 12. the source of energy in a circuit
- 13. more than one cell
Down
- 1. can be used to vary the current
- 2. the unit of current
- 5. the unit of resistance (what it is measured in)
- 8. this only lets current flow one way
- 9. lights up
- 10. a very small light bulb made from a diode
