Electricity

Electric Current

The flow of electrons through a conductor. The device which causes the flow of electrons through a conductor is called cell.

Electron Flow

From the negative terminal to the positive terminal.

Conventional Current

From the positive terminal to the negative terminal.

Electric Current

The rate of flow of charges through a conductor or the quantity of charges flowing through a conductor in unit time.

Electric Circuit

A closed path that allows electric current to flow from a power source, through components, and back to the source.

Ohm’s Law

A relationship between the potential difference across a conductor and the current flowing through it.

Ohm’s Law

The current flowing through a conductor is directly proportional to potential difference between its ends provided its temperature remains constant

Series Circuit

Electrons only have one path to flow through.

Parallel Circuit

There are MULTIPLE paths for the current to flow trough.
