AcDc Flashcards
What does an alternator produce
Alternate Current
What does an genarator produce
Direct Current
Alternator/Genatrator Outputs
What happens when the loop rotates around?
In the magnetic field it cuts the magnetic flux between the two magnets
And cuts more or less magnetic flux depnding on the position
Alternator/Genatrator Outputs
What does it cause when cutting more or less of the magnetic flux?
It cuases the EMF to become weaker or stronger depending on the position of the loop in the field
Alternator/Genatrator Outputs
What would happen to the EMF if it was horizantal or vertiacal?
If horizantal the EMF would be greately induced, as for bring vertical, the EMF would not be induced
What is it called when genaration rise and falls between positive and negative?
A sinwave
How to get a smoother out put wave form?
More segments
What are the commonways to make DC?
- battery of cells
- Photovoltaic cells
- DC genatrator
- electronics (the use of a rectifier)
What does arechifier do?
Changes AC to DC
What does Inverter do?
Changes DC to AC
How to get a better waveform and more consistant supply?
By using full wave certifieror bridge rectifier
How to get a smoother DC supply?
Connectiing a capacitor in parallel with the output from the bridge rectifier
How to find the ameter of max value?
F=1/T
Frequency
Time
How to find RMS?
Peak valu x 0.707
How to find average voltage?
Max voltage x 0.636
