Two lamps connected in series with ... same throughout a circuit and voltages add up to the supply voltage. Components that are connected on separate loops are connected in parallel.

Using circuit simulating software like SPICE ... and the user can specify parallel and series connections using special operators. Not only can the program calculate the combined impedance but ...

In series circuits, the current is the same through each component. The potential difference of the power supply is shared between the components. A parallel circuit showing two bulbs, a switch ...
