The supply voltage is shared between components in a series circuit, so the sum of the voltages across all of the components in a series circuit is equal to the supply voltage, V s.

Calculating Series Voltage Drop Series voltage drop is the progressive loss of voltage that occurs when feeding a string of parallel-connected loads. It's of particular concern when feeding a string ...

In National 5 Physics examine the current and voltage in series and parallel circuits to formulate rules and determine unknown values.
