current electricity | the continuos flow of charge in a complete circuit. |
electric circuit | a complete a pathway that allows electrons to flow. |
electric current | the amount of charge passing a point in a conductor. |
electric load | any device that transforms electrical energy into other forms of energy, such as a light bulb, buzzer, heater and motor |
electric potential energy | electric energy stored in a battery |
electric resistance | the ratio of voltage to current |
electrochemical cells | electrodes in electrolytes that convert chemical energy stored in charges. |
electrodes | two terminals in a battery or other electricity source. |
energy | the ability to do work. |
kinetic energy | energy a moving object has because of particles in matter. |
ohm | the unit of measurement for electrical resistance. |
ohmmeter | a device that measures resistance. |
Ohm’s law | the mathematical relationship comparing voltage (V), current (I), and resistance (R), written as R=V/I |
Potential difference | the amount of electric potential energy per on coulomb of charge at one point in a circuit compared to the potential energy per coulomb of charge at another point in the circuit; also called voltage. |
resistance | the property of any material that slows down the flow of electrons and converts electrical energy into other forms of energy. |
resistor | an electrical component with a set amount of resistance that slows down current and transforms electrical energy into other forms of energy. |
terminals | the positive and negative end points of a battery. |
volt | the unit of potential difference |
voltage | the amount of electric potential energy per one coulomb of charge at one point in a circuit compared to the potential energy per coulomb at another point in the circuit. |
Voltmeter | a device that measures the amount of space taken up by a substance or object, usually measured in liters (L) or cubic centimeters. |
