Electricity 1

2. A 'thousandth' of an Amp.
3. Equivalent to a 'Joule per second'. Often seen on light bulbs.
7. A law, named after a physicist, that states the total current flowing towards one point is equal to the current flowing away from it.
10. The unit of potential difference.
11. The current always stays the same in this type of circuit.
12. Voltmeters must always be connected to a circuit in this way.
14. The total resistance (RT) of two 330 Ohm resistors in parallel.
15. This coloured band on a resistor has a value of '3'.
16. A special type of resistor which changes its resistance according to the level of light.

1. The type of current which can flow in both directions in a circuit.
4. A piece of equipment used to measure electrical current.
5. Multiple cells join to make a...
6. The unit of capacitance
8. A material which is an example of a good conductor.
9. The symbol for this component is a circle with an 'M' inside it.
13. A component which only allows current to flow in one direction through it.
