The push or pull one object exerts on another.
A positively or negatively charged atom.
An imbalance of electric charge on an object and is due to the transfer of electrons between objects.
Force all charged objects exert on each other-charges can be attractive
Surrounds electric charge-exerts force on other electric charges.
Material in which electrons can not move from place to place like plastic, wood, glass, bad rubber.
Material that contains electrons that can move easily in the material like electric wire, copper, gold, and aluminum.
Rapid movement of excess charge from one place to another like lighting.
Gravitational potential energy
Energy stored in an object due to position above earths surface.
Source of electrical energy-is the flow of electric charge.
Electric charge flows continuously only through closed conducting loop.
Measure of how much electrical potential energy each electron can gain. Voltage is measured in volts (V).
The measure of how difficult it is for electrons to flow through material. The unit of measure for resistance is the ohm.
The rate at which energy is transferred; it equals the amount of energy transferred divided by the time over which the transfer occurs.
The relationship between voltage, current, and resistance in a circuit. Voltage= current x resistance.
A circuit that has only one path for the electric current to follow.
A circuit that has more than one path for the electric current to follow.
The rate at which electrical energy is converted into other forms of energy. Power= current x voltage.
