The smallest particle of an element that retains the properties of that element.
What is an Atom.
100
The ability to do work.
What is Energy.
100
Unit of measuring electric current; very small currents are measured in milliamperes (mA); 1 A = 1000 mA.
What are Amperes.
100
The unit of measurement for electrical resistance.
What is Ohm.
100
A protective mechanism in an electric circuit; contains a metallic conductor strip that melts when excessive current passes through it, thus opening the circuit and stopping electron flow.
What is Fuse.
200
Positively charged particle in the atomic nucleus.
What is a Proton.
200
A combination of electrochemical cells connected together (or a single electrochemical cell) that produces a potential difference.
What is a Battery.
200
A complete pathway that allows electrons to flow.
What is an Electric Circuit.
200
An electrical component with a set amount of resistance that slows down current and transforms electrical energy into other forms of energy.
What is a Resistor.
200
A circuit that has only one path for current to travel.
What is a Series Circuit.
300
Negatively charged particles surrounding the atomic nucleus.
What are Electrons.
300
The unit of potential difference; one volt cause a current of one ampere to flow through a conductor with a resistance of one ohm.
What is Volt.
300
The amount of charge passing a point in a conductor every second.
What is an Electric Current.
300
The property of any material that slows down the flow of electrons and converts electrical energy into other forms of energy.
What is Resistance.
300
An electrical circuit that has more than one path.
What is a Parallel Circuit.
400
Negatively charged particles surrounding the atomic nucleus.
What is Grounding.
400
Two terminals in a cell or other electricity source; usually made of two different metals or a metal and another material.
What are Electrodes.
400
Any device that transforms electrical energy into other forms of energy, such as a light bulb, buzzer, heater, or motor.
What is an Electric Load.
400
The ratio of voltage to current.
What is Electrical Resistance.
400
The location where a circuit divides into multiples paths or where multiple paths combine.
What is a Junction Point.
500
An electric charge that can be collected and held very nearly fixed in one place.
What is Static Charge.
500
Substance that conducts an electric current; in a dry cell. the electrolyte is a moist paste; in a wet cell, the electrolyte is a liquid.
What is an Electrolyte.
500
The continuous flow of charge in a complete circuit.
What is Current Electricity.
500
The mathematical relationship comparing voltage (V), current (I), and resistance (R), written as R = V/I.
What is Omh's Law.
500
The round prong of an electrical plug; allows excess current flow from an electrical device to ground to prevent electrical shock.
