When resistors are connected together in series, we can add their resistances together to find the total resistance in the circuit.

Previous tutorials have described that resistors may either be connected as a series circuit or a parallel circuit where the currents and voltages are obtained using Ohm’s Law. To produce more complex ...

material, eg copper, has lower resistance than steel length - longer wires have greater resistance thickness - smaller diameter wires have greater resistance temperature - heating a wire increases its ...
