Right. So my advice would be... make the circuit ! Make the circuit and see if the current is limited to the value of the current supply. Ensure in reality that the current source is rated for at least the voltage of the battery, though ! and vice versa for current ! The discussion here has...

Sure. Let me answer your question with a question. In your series circuit, what is the voltage drop across the current source? Would you agree that, if the current source drops voltage, any voltage, that it limits the amount of current that the battery injects? My understanding is that the...

You see, the current injected by the battery is determined itself by the current source. Current sources behave that way. That is, they drop voltage supplied externally (in your case the battery) and they just supply current. If this makes sense and you are looking for a way to remember it...

No apologies required ! I love the discussion.. The current sources would drop sufficient voltage to limit the current supplying capabilities of the voltage source to levels dictated by the current sources themselves. The current sources don't 'pick-up' the current injected by the battery and...

The battery can't deliver 50mA in pt A. It can't deliver more than the current sources are drawing.

Sure. Have you ever read about what constitutes a current source? like you already know batteries and generators are examples of voltage sources right? what is an example of a current source? have you studied transistors yet? This is something that comes up in very basic transistor circuits...

No the current source's value will determine total circuit current is my understanding of this. The voltage developed across the resistor will then be determined by ohm's law, and the voltage developed across the current source will be determined by the value of the battery voltage. The amount...

If you have a single loop and you know the value of current through anyone component, isn't that the value of the current through out the circuit? In this circuit the current source dictates the current. The voltage source would dictate the voltage level. The ideal current source allows any...

Replace the five current sources by a single 5 mA current source in series with a battery and resistor. What would be the value of 'i' then?

Not a problem

Only time the source current isn't flowing (is 0) is from $$0 - \alpha$$ $$\pi - (\pi+\alpha)$$ $$2\pi - (2\pi + \alpha)$$ $$\vdots$$ Unlike the output current, the source current flows in two directions depending on which rectifiers are on

It would make sense to me if the pink was the voltage across T1 and the voltage across D2, since they conduct during the positive half cycle of Vs, and do not conduct during the negative half cycle of Vs.

Not sure where the waveforms are

I swear this looks exactly like an old professor of mine hand writing (uddin?) To answer your question - the Vout waveform goes to zero because both controlled rectifiers (T1 and T2) are not conducting (reverse biased). Are you aware that inductors oppose changes in current by creating their...

Probably should be seeing it, but I'm not
