Static electricity is

The buildup of charge on a surface as a result of gaining or loosing electrons through friction with another surface

1

If object has gained electrons it is a what charge?

Negatively charged

2

If object has lost electrons it is a what charge?

Positively charged

3

Static situations

Hair sticking on brush
Electric shock
Escalator

4

Law or charges States that

Opposite charges attract
Likes charges repel

5

Static electricity is produced by

Friction between two different materials

6

Electrostatic. Induction

Temporary buildup of charge on a neutral object due to the presence of a charged object

7

Explain why spray painting with a charged object is better to use?

The charged object will induce a charge on the paint droplets and the object will attract the paint making it unwasted

8

What do current electricity need?

Voltage source
Complete circuit made by conducting materials
A load

9

Current electricity

Where charged flow along a path

10

Conductors examples

Copper
Aluminium
Graphite
Iron

11

Insulator

Glass
Plastic
Wood
Rubber

12

Voltage is ? EMF

A measure of the amount of energy available to push charges around a circuit.

13

Potential difference

Measure of how much energy is transferred or used by a load

14

Voltage in parallel

The voltage is the same across all branches

15

Series in voltage

The voltage is shared

16

Parallel current

The current splits at each branch and thy add up to the total current

17

Current series

Current is the same everywhere
