A series of free GCSE/IGCSE Physics Notes and Lessons.

In this lesson, we will

• Describe what is meant by a series circuit.

• Describe what is meant by an electric current.

• Describe the pattern of current flow in a series circuit.

An electric current is a flow of electric charge around a circuit. This moves from the negative end of the cell to the positive end. However, scientists always draw the current in the opposite direction. We call that the conventional current.

The unit of electric current is the ampere (A). We can measure the current in a circuit by using an ammeter.

A series circuit has no branches. The current can only flow in one path.

In a series circuit, the current is the same all the way round.

**Current in series circuits**

Current is the same everywhere in a series circuit.
