ammeter a device used to measure the current in a circuit.
amperes unit for measuring electric current.
battery a combination of electrochemical cells connected together that produces a potential difference.
circuit diagram a drawing using symbols to represent the different components of a circuit.
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.
