ALTERNATING CURRENT - NCATT

Operation - Half-Wave Rectifier• The positive voltage felt on the anode of CR1 willforward bias it• Majority current flows AGAINST the arrow• Current will flow from the bottom of the secondary,through R L , through the diode, and back to the top ofthe secondary• Since R L is very large, it will drop (develop) nearly allthe secondary voltage across R L , and it represents thepositive half of the AC input voltage• We disregard the voltage drop across the forwardbiased CR1
