03. Electrical current

Current can be defined as : the number of groups of electrons passing a point in a circuit per second. It is measured in Amps and can be measured in a circuit by using an ammeter.

The following presentation has information about current and how current behaves in circuits. Yu should be able to predict current readings for any position in a  circuit if given the original current reading from the battery.

Carry out this practical to explore current laws. You can do this i the lab, or using an online simulation.

Here are some problems to solve to check your understanding of current.
