charge - Electric charge is a basic property of matter that causes forces between charged particles or objects. It can be positive or negative., cell - A chemical store of energy that can be transferred by electricity., battery - More than one cell joined together., series circuit - A type of circuit with only one loop of wire., parallel circuit - A circuit in which there is more than one path for the current to follow., voltage - The energy transferred to or from a coulomb of electric charge when it flows between two points., current - A measure of how many coulombs of charge pass a point in the wire every second., ammeter - A meter used to measure current., voltmeter - Meter used to measure potential difference (or voltage)., ampere (A) - The unit for current. Can be shortened to amp., volt (V) - The unit for potential difference (or voltage)., coulomb (C) - The unit for measuring charge., ohm (Ω) - The unit for measuring electrical resistance., potential difference - The energy transferred to or from a coulomb of electric charge when it flows between two points. Sometimes called voltage., resistance - A measurement of how difficult it is for electricity to flow through something., diode - A component that lets electric current flow through it in one direction only., light-dependent resistor (LDR) - A resistor whose resistance gets lower when light shines on it., thermistor - A component whose resistance changes as its temperature changes. The thermistors increase in resistance as the temperature increases.,
