Closed conducting loop through which an electric current can flow.
Material, such as copper wire, through which an excess of electron can move easily.
A type of chemical cell, commonly used today, in the form of batteries, for many electrical appliances. It uses a paste electrolyte, with only enough moisture to allow current to flow.
The electric force per unit charge; it is radially outward from a positive charge and radially in toward a negative point charge.
Flow of electric charge through a wire or any conductor; measured in amperes, A, in a circuit.
Rate at which electrical energy is converted to another form of energy; expressed in watts, W.
Material that does not allow electrons to move through it easily.
Unit of electrical energy, which is 1000 watts of power used for one hour.
Law of Conservation of charge
States that charge can be transferred from one object to another but cannot be created or destroyed.
A metal rod or metallic object mounted on top of an elevated structure, such as a building, a ship, or even a tree, electrically bonded using a wire to interface with the through an electrode, engineered to protect the structure in the event of lightning strike.
States that the current in a circuit equals the voltage difference divided by the resistance.
Circuit in which electric current has more than one path to follow.
Tendency for a material to oppose electron flow and change electrical energy into thermal energy and light; measured in ohms.
Circuit in which electric current has only one path to follow.
Electricity generated when more than one type of charge is on an object
Push that causes electrical charges to flow through a conductor; measured in volts.
An electric battery is a device consisting of two or more electrochemical cells that convert stored chemical energy into electrical energy using a liquid electrolyte
Electrical current where the flow repeatedly changes direction.
Electrical current that flows in one direction from the negative to positive terminal.
