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
