Electricity and Magnetism
Electricty
Static Electricity
Static electricity is a buildup of electric charges on objects
Friction
Electric charges can build up through friction
Charge
Positive
The object that gives up the electrons
Negative
The object that accepts the electrons
Static Discharge
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.
Electric Field
Test Charge
An object that has negligible charge
Electric Field Stength
E is used to represent electric field strength. E=F/q
Non-Contact Force
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.
Curcuits
Current
Electric current is a continuous flow of electric charges
Ampers
Often shortened to "amp", is the base unit of electric current.
Voltage
Measures the electric potential difference across two points.
Resistance
Resistance is opposition to the flow of electric charges in an electric current as it travels through matter.
Electromagnet
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
Series
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
Parallel
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.
