1. Protons: positive charge

2. Electrons: negative charge

3. Neutrons: no charge

Insulators

Conductors

Visible attraction

Repulsion

Electrical sparks

This chargeimbalance

is the origin of “Static

Electricity”

Combing your hair moves electrons from your hair to the comb

The comb will now have an electric static charge

The basic fundamental principle behind thisapparatus is separating opposite charges atboth ends of the rubber belt

I. MotorII. Upper and lower

roller III. BeltIV. Upper and lower

brush V. Metal sphere

As the belt keeps running, more charges are deposited on both pulleys

1) Materials involved

2) Surface area connecting the materials

3) Humidity

Static electricity can build up in ourbodies and cause a spark to jump fromour bodies to pieces of metal or thosein our surroundings
