Farad

(F) The SI unit of capacitance.

Circuit

A complete loop where electricity can flow from start to finish

Charge

A property of an elementary particle that determines the strength of its electric force with other particles that also have ______. Measured in coulombs.

Inverse Square Relationship

A relationship where a quantity is related to the reciprocal of the square of a second quantity. Examples include the force laws for gravity and electricity; the force is proportional to the inverse square of the distance.

Electricity

Current

The amount of charge that passes a point in one second. The flow of electric charge, measured in amperes.

Resistance

The impedance to the flow of electric current; measured in volts per ampere, or ohms. The __________ is equal to the voltage across the object divided by the current through it, _=V/I.

Power

The rate at which energy is converted from one form to another. Measured in joules per second, or watts. In electric circuits the _____ is equal to the current times the voltage, _=IV

Ohm's Law

The resistance of an object is equal to the voltage across it divided by the current through it, R=V/I
