Basic electricity Current: this is the flow of electric charges

around a circuit. The size of the current is dependent on the rate of flow of electrical charges.

Potential difference: (voltage) the potential difference between two points is the work done per unit charge between two points.

Resistant: This is the resistance to the flow of the electrons around the circuit.

Circuits There are two types of circuits parallel

and series.

Summary The summary of this PowerPoint is that

electricity does not like to be restricted as showed by the resistance table and the video on slide 5.

So the overall Idea is that the thicker the wire the less resistance there will be in the wire so that there will be a greater flow of electricity.
