Vocabulary List

Electricity Generation

Non-Renewable: A nonrenewable resource is a natural resource that can not be rapidly replaced naturally.

Examples: Coal, gas, oil, nuclear energy, natural gasses.

Renewable resources: A renewable resource is a natural resource that can be re made by the earth often.

Examples: Lightning, solar energy, hydro energy, wind energy, biomass energy, trees and lumber

Static Electricity

Laws of Electro-Static

Repulsion: Like Charges Repel <- (+) (+)->

Attraction: Opposite charges attract each other (-)-><- (+) Charged and neutral objects attract each other. (n) -><- (+)

Flow Of Electricity

Conductors: Conductors are materials that allow electrons to flow freely from particle to particle.

Examples: Good conductors are metals that are ductile/can be pulled into wires. Some metals that are often used are copper, steel, gold aluminum, iron etc.

insulators: Insulators are materials that impede the flow of electrons from atom to atom.

Examples: yarn, plastic, cloth, rubber, and wood.

Parts of an atom

Electron: Electrons are found in orbit around the nucleus. Electrons are negative and they have a charge of (-1)

Neutron: A neutron is a subatomic particle found inside of the nucleus. Neutrons are neutral and have a charge of Zero.

Proton: A proton is a subatomic particle found in the nucleus. Protons are positive and they have a charge of (+1)

Methods of Charging

Charging By Induction: Charging by induction is when an object is charged without direct contact. Bringing a charged object close to a neutral object will induce the same charge in the neutral abject.

Charging By Contact: Charging by contact can only occur by contact through the transfer of electrons. When charging by contact there must be a difference in the amount of charge between the two objects.

Charging By Friction: Charging be friction happens when 2 rubbing two different typed of ebjects together will transfer electrons from one object to the other. when charging is the transfer of electrons, protons and neutrons do not move/transfer.

Electrical circuits A continuous path that electrons can flow through. There are two types of circuits.

Series circuit: A series circuit only has 1 path that current/electrons flow through and the electrons push each other ahead.

Parallel Circuit: Parallel circuits have more than 1 pathways that current/electrons flow through. Parallel circuits have branching points where the current can flow along different paths.

Power Source

A power source is a source of power.

Example: A power source is often a battery or a generator.

Ohm Law

Wattage/Watts: Wattage is a method of measuring the rate of energy transfer of an appliance. You can find wattage by multiplying the voltage by the current.

Resistance: (R) Resistance is a physical property that describes how a material impeded the flow of electrons.

Voltage: (V) Voltage is a measure oft the amount of energy per coulomb.

Voltmeter: Voltage is measured using a device called a voltmeter. The voltmeter measures the electric potential in volts.

Potential difference: Potential difference is the difference in voltage between two points.

Current: (I) Current is the movement/flow of electrical charge/ electricity. Current is the measurement of how much charge passes through a point in one second. Current is represented using the symbol (/)

Ammeter: Current is measured using a device called an ammeter.

Amperes/Amperage: Current is measured in units known as amperes/amps. Amperes is the SI base unit of electrical current.
