Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits. We can calculate the voltage, current and resistance in these circuits.

In a series circuit, the identical current passes through every component connected in the circuit. Conversely, in parallel circuits, components are arranged side by side, causing the circuit to ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. Electrical circuits can be connected in parallel or in series ...

The series circuit is a single closed loop, as you can see. But a parallel circuit provides multiple loops. If you stack the loads on top of each other ladder-rung-style in your drawing, they are in ...

In this case, there is just one path for the current to follow. The current that goes through the first bulb also goest through the second bulb. If you remove any part of this circuit (like take ...
