Electricity basics
electrical charges build up on the surface of an object
What is static electricity?
allows electricity to flow through it
What is a conductor?
has one path for electricity
What is a series circuit?
works as a result of a chemical reaction and the movement of electrons
What is a battery?
discovered that current traveling through a wire produces a weak magnetic field
Who is Hans Christin Oersted?
The continuous flow of electrons around a cirucuit?
What is current electricity?
the switch is closed and electricity flows freely
What is a closed circuit?
has multiple paths for electricity
What is a parallel circuit?
What is an electrolyte?
electronic devices
What uses electricity to communicate information?
a continuous unbroken path through which electricity can flow
What is a circuit?
What is a resistor?
the amount of electrical push or force
What is a volt?
turbines
What is used by most power plants to make electricty?
The brain of a computer
What is the Central Processing Unit?
this occurs when an object has a positive or negative charge
When does an object have electrical force?
a continuous flow of electrons
What is needed for electricity to be useful?
The measurement of power used
What is a Watt?
a machine that converts motion into electrical energy
What is a generator?
a coil of wire attached to an electrical source
What is an electromagnet?
amber produced a spark when rubbed with fur
plastic, wood, and glass
What are examples of insulators?
Watts/Volts or how much power flows through a given circuit
What is an ampere?
moving a magnet around a loop of wire or moving wire between north and south poles
How magnetism makes electricity?
Discovered that adding a metal core to a coil of wire increased magnetism
Who is William Sturgeon?
