wind speed
effect (swept area)
air density
anemometer
measures speed of wind
pitch
angle of wind turbine’s blade (changes amount of energy created)
wind vane
measures direction wind is blowing
ohm’s law
V=IR
shows the relationship between current, resistance and voltage
I and V= direct relationship
R and V= direct relationship
I and R= indirect relationship
work and power
power= work/time taken
work= force x distance
