No, it's your turn to finish explaining and answering questions first. Ask WW1WW for help if needed. Answer all of the following questions. Question 1: Go back and answer the simple questions. (Without getting into a convoluted discussion, of course.) Figure 1: What does the current coming out of the source look like? Check only one answer below. (Keep it simple now) •____ 1 amp pulses matching the resistor current exactly? •____ A constant flat DC current of 0.25 amps? Figure 2: What will the current coming out of the supply be? Check one. Keep it simple. •____ A full wave rectified sinewave of current with peak value of 50 mA matching the collector current exactly? •____ A flat DC current equal to the average value of the collector current or 0.637 x 50 mA = 31.85 mA? Question 2: Just tell me (no convoluted discussions) how a DC supply works. I'll start you off. A DC supply will work very hard to keep the voltage constant. Now you tell me what a DC supply does regarding current. Keep it simple! Question 3: Describe what the current looks like just as it enters the center tap of the bifilar feed coil. ie; full wave rectified pulses of current essentially replicas of the individual transistor current pulses, or a dead flat DC current equal to the average of the transistor current pulses. Question 4: If you say the current entering the center tap is a dead flat DC equal to the average of the transistor current pulses then explain when Q1 first turns on but the collector/drain current has only risen to a few milliamps but the current coming out of the DC supply is a flat DC of about 10 amps, all those extra amps and electrons are going (fill in the blank) ____________________ . Question 5: Does WW1WW's assertion that all those extra electrons representing the unexplained 10 amps of question 4 are converted into stored energy in the magnetic field sound plausible to you? Keep it simple now, like maybe YES or NO. If so, can you or WW1WW provide a valid physics reference that supports this new "discovery"? Question 6: Does WW1WW's assertion that all those extra electrons representing the unexplained 10 amps of question 4 are leaking through the off transistor seem plausible to you? Simple now, should be a YES/NO answer. Either you agree with him or you don't. Question 7: What is "Pure DC" (no convoluted discussions) You and WW1WW throw it around like it has some special meaning. I have been taking it to mean the voltage is constant but the DC supply will provide whatever current the connected load demands or asks for because that's all a DC supply can do. I think you and WW1WW think that "Pure DC" has some extra meaning. So please explain in simple terms what you are assuming when you say at point B you have Pure DC.
