Parallel Circuit Calculations provides a comprehensive overview of the rules and formulas used to calculate electrical quantities and capacity. Using a direct current parallel circuit as an example, ...

In other words, the current is the same at all points in a series circuit ... Any components in parallel have the same potential difference across them. In order to calculate the total resistance ...

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.
