Crossed Circuits

3. A type of diode which emits light when current passes through it in one direction. It does not emit light when current passes through it in the opposite direction.
6. A component which limits the flow of electric current in a circuit by keeping the resistance constant.
10. A circuit in which the current divides into two or more paths before recombining to complete the circuit.
11. A component used to measure the electric current flowing through a circuit. It is connected in series.
12. A type of resistor which causes the resistance of the circuit to decrease as the temperature increases.
13. A component that can be open or closed. When it is open a gap is created in the circuit meaning current cannot flow.
14. A component used to measure the potential difference across a component in a circuit. It is connected in parallel to the component across which the potential difference is being measured.
15. A component containing a thin wire that melts if too much current passes through it. It is used as a safety device in a circuit.

1. A component that transfers energy from its chemical store to cause an electric current to flow through a circuit. Two or more of these connected in series is called a battery.
2. A component used to control the current flowing through the circuit by changing the resistance.
3. A resistor that causes the resistance of a circuit to decrease as the light intensity increases.
4. A component which only allows current to flow in one direction.
5. A component that emits light when current flows through it. It can also be called a bulb
7. A circuit in which the current follows one path.
8. Two or more cells connected together in series.
9. Thin strands of metal which carry electric current between circuit components.
