Electricity and Magnetism
Static electricity is a buildup of electric charges on objects
Electric charges can build up through friction
The object that gives up the electrons
The object that accepts the electrons
A sudden flow of electrons between a negatively and positively charged areas.
Can be found in lightning bolts and when you touch something and get a shock.
An object that has negligible charge
Electric Field Stength
E is used to represent electric field strength. E=F/q
A force which acts on an object without coming physically in contact with it.
An electric field surrounds an electric charge, and exerts force on other charges in the field, attracting or repelling them.
Electric current is a continuous flow of electric charges
Often shortened to "amp", is the base unit of electric current.
Measures the electric potential difference across two points.
Resistance is opposition to the flow of electric charges in an electric current as it travels through matter.
An electromagnet is a coil of wire with electric current flowing through it wrapped around a bar of iron or other ferromagnetic material.
Types of Curcuits
A circuit that consists of one loop is called a series circuit. If a series circuit is interrupted at any point in its single loop, no current can flow through the circuit and no devices in the circuit will work
A circuit that has two loops is called a parallel circuit. If one loop of a parallel circuit is interrupted, current can still flow through the other loop
A closed loop through which current can flow is called an electric circuit.
