STATIC ELECTRICITY
Concept of Static Electricity
Detection of Charges
Conductors and Insulators
Difference between a Conductor and Insulator
Distinguish between a conductor and insulator
Conductors
Are bodies, which readily allow electric charge in motion to flow through them
OR
Are materials that permit some electrons to flow freely from atom to atom within the materials examples are copper, steel, iron, silver and gold.
When there is excess of positive or negative charge on an object made of a conducting material, the conduction electrons will move to minimise the repulsive force.
Insulators
These are bodies, which do not allow electric charges to flow through it. Insulators on the other hand do not allow their electrons to flow freely from at atom to atom; this is because the electrons in their atoms move around their nuclei in various equal magnitudes to the charge on the protons. The electrons are also firmly attracted to the nucleus hence bound to these atoms.
