Current in series circuit

What happens if we close a switch in a complete circuit

Electrons flow out of the cell and move around the circuit. We call this flow fo electrons an electric current

How does an electric current flow

From the negative end of the cell to the positive end

What does the electrons carry

Energy. They pass this energy to components in the circuit such as a lamp

What happens in a lamp in an electrical circuit

The electrical energy is transferred to light energy and thermal energy

What happens when electrons return to positive end of cell

When they return they are carrying less energy than when they left the negative end.

How do we show an electric current

An arrow

What is conventional current

Scientists use to think electric current travelled from the positive end to the negative end, so we still draw the arrow going this way

What is a series circuit

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

Electric current definition

A flow of electric charge around a circuit

Definition of electric current

Ampere (A)

How do we measure current

Using an ammeter

Current in a series circuit:

Current is never used up in a circuit. In a Series circuit, the current is the same all the way around
