I - V CHARACTERISTICS
POTENTAIL ENERGY
measured in volts
FILIMENT LAMPS
as temperature increases resistance increases
OHOMIC CONDUCTORS
current is directly proportional to potential difference
applies at temperature constant
resistors
resiatance stays constant
DIODES
current can only flow in one direction
MAINS ELECTRICITY
EARTH WIRE: green and yellow stripes
Prevents appliances from becoming live
NEUTRAL WIRE: blue
Completes the circuit
LIVE WIRE: brown
Mains electricity voltage is 230V
STATIC ELECTRICITY
Rubbing insulating materials together rubs electrons off one material and onto the other
Materials gaining electrons become negatively charged
Charged object produces an electric field around itself
Field lines point from positive to negative
