Potential difference=

Energy / charge

3

Resistance=

Voltage / current

4

A charged atom is called an...

...ion

5

Some ions are...

...charged when they are rubbed as electrons are transferred

6

Like charges...

...repel

7

Unlike charges...

... repel

8

Current is...

...the flow of charge which are electrons

9

In a series...

... the current is the same on each component
...the voltage of the power supply is the same in each component
... the total resistance in the circuit is equal to the sun of the current

10

In a parallel circuit...

...the total current is equal to the sum of the current
.... the voltage across each component is the same
