ICT 9 Q3 M6

Define as the flow of electron or electric current. It is an invisible form of energy that can be transform into other form of energy like heat light and mechanical.

• Electricity

• Matter

• Atom

• Proton

The negatively charge component of an atom. It has the ability to flow.

• Electricity

• Electron

• Atom

• Proton

The positively charge component of an atom. It has the ability to attract electron.

• Electricity

• Electron

• Atom

• Proton

Same as electricity or flow of electron. The amount of current flowing in a circuit can be measured in ampere (I).

• Current

• Resistance

• Voltage

• Conductor

These are materials that easily allow the flow of current, or it has a low resistance to current flow.

• Insulators

• Resistance

• Voltage

• Conductors

These are materials that do not easily allow the flow of current, or it has a high resistance to current flow.

• Insulators

• Resistance

• Voltage

• Conductors

In this type of current, the flow of electric charge is only in one direction. This is the type of electricity is produced by batteries, static, and lightning.

• Direct Current

• Current

• Alternating Current

• Voltage

The movement of electric charge periodically reverses direction. This type of electricity is produced or generated by AC generators commonly from a hydro-electric plant. It is the commercial power that we use in homes and offices.
