Alternating Current (AC) 
What can an alternator produce
Direct Current (DC) 
What does an generator produce
In a magnetic field, it cuts the flux between magnets, varying with position. 
What happens when the loop rotates around
Measured in degrees or time 
How can sine waves be measured
By connecting a capacitor in parallel with the output from the bridge rectifier 
How is smoothing DC achieved
RMS = peak value x 0.707 
How to calculate RMS of a sine wave
Peak value = RMS/0.707or RMS value x √2 (1.41) 
How to find Peak value
Average value sine wave = peak value x 0.637 
How to find average value sine wave
Peak value = average value/0.637 
How to find peak value
T=1/F
How to fin periodic time
F=1/T 
How to find frequency
