Words and meanings to learn
current
How much charge flows past a point in the circuit each second. Measured in amps (A).
charge
The amount of electricity carried by particles like electrons. Measured in coulombs (C).
potential difference (voltage)
The energy given to each coulomb of charge in a circuit. Measured in volts (V).
resistance
How much a component slows down the flow of current. Measured in ohms (Ω).
ohm's law
A rule that says potential difference = current × resistance for a wire at a constant temperature.
