| series circuit | a circuit with only one pathway for the current |
| parallel circuit | a circuit with more than one pathway for the current |
| junction | a place where two or more wires meet |
| resistance | ability of a substance to decrease the flow of current; measured in ohms (Ω) |
| resistor | a device used to control current in a circuit by causing resistance |
| variable resistor | a component that can be adjusted to give different amounts of resistance |
| *short circuit | a situation caused by electricity taking an unexpected path |
| *volt (V) | unit of measurement for the amount of electrical push in a circuit |
| *voltage | a measure of how much energy the electrons are carrying around to the things in a circuit; also the measurement of the amount of electrical ‘push’ in a circuit |
| *voltmeter | a device that measures voltage in a circuit |
| *circuit breaker / power breaker | a device that trips like a switch and opens the circuit when overloaded (too much current flows through the circuit) |
| *grounding / earthing | to connect an electric circuit to the ground for safety purposes |
