- signal information by opening and closing electrical circuits in sequence
- Central Processing Unit (CPU)
- brain of the computer that tells the other parts of the computer what to do
- ampere
- measures how much current flows through a given part of a circuit in one second
- volt
- measures the amount of electrical push, or force, in a circuit
- watt
- measures power, or how fast work is done
- electromagnet
- coil of wire with a core attached to an electrical source
- resistor
- filament in a light bulb
- Joseph Henry and Michael Faraday
- discovered that moving a magnet around or through a loop of wire produces electricity in the wire
- Hans Christian Oersted
- discovered that current traveling through a wire produces a weak magnetic field in the live wire
- William Sturgeon
- discovered that adding a metal core to a coil of wire increased the magnetism
- current electricity
- flow of electrons around a circuit
