Electricity/Units
A measurement of the amount of electrical push, or force, in a circuit.
volt
The brain of the computer
Central Processing Unit (CPU)
A continuous unbroken path through which electricity can flow.
circuit
Any material that has the ability to attract iron.
magnet
True or False. The strength of an electromagnet is determined only by the amount of electricity it receives.
False
Measures power, or how fast work is done.
watt
Stores information temporarily.
Random Access Memory (RAM)
A circuit with multiple paths for the electricity to flow.
parallel circuit
The magnetic force of a magnet is strongest at the ________ of the magnet.
True or False. The strength of an electromagnet can be affected by the size of the core or the number of coils around the core.
True
Unit used to measure the amount of electric current flowing through any given part of a circuit in one second.
Ampere (amp)
Built-in memory and programs of the computer.
Read-only-memory (ROM)
A circuit that has only one path, or one circuit, for the electricity to travel.
series circuit
The area of magnetic force around a magnet.
Faraday, Henry, Oersted, or Sturgeon. Discovered that current traveling through a wire produces a weak magnetic field in the live wire.
Hans Christian Oersted
1000 watts
kilowatt
Daily Double
A tiny wafer of semiconducting material used to make an integrated circuit for a computer.
Occurs when electricity takes an unexpected path.
short circuit
A coil or wire attached to an electrical source and wrapped around a metal core.
electromagnet
Faraday, Henry, Oersted, or Sturgeon. Which two discovered that moving a magnet around or through a loop of wire produces electricity in the wire.
Joseph Henry & Michael Faraday
The flow of electrons around a circuit.
current electricity
The __________ system uses open and closed circuits to communicate the numbers 0 and 1.
binary number
A very small circuit with all the parts built into it.
integrated circuit
A machine that uses a magnet to convert motion into electrical energy.
generator
Faraday, Henry, Oersted, or Sturgeon. Discovered that adding a metal core to a coil of wire increased the magnetism.
William Sturgeon
