What are the 3 electrification methods

Friction, contact, induction (induces a charge in a nearby object without touching it)

What’s the term for the “unit of electrical charge”

Coulomb

What coulomb equation creates a positive charge

6.3 × 1018 electrons

True or false in solid objects, charge will concentrate at the greatest curvature of the surface

True

what do semiconductors do and what is it primarily made of

allow electricity to flow only under certain specific conditions. Made of silicon, cement & germanium

Does Increasing distance increase or decrease the charge

Decreases

what do conductors do and what is it primarily made of

allows electricity to pass through easily. primarily made of medals, dirty water

what do insulators do and what is it primarily made of

resist the flow of electricity. Made of plastic, rubbers, oil, pure water

Define ampere (A)

1 coulomb per second

To have a electrical circuit what 3 components are required

1) a conductor

2) a source of electromagnetic force (EMF) - a battery

3) an operated device that acts as a electrical resistor in the circuit
