Yes and no...
I've been asked to look through an exam question for a training course, but I can't make head nor tail of it. I'm tempted to say this question doesn't make sense, but I thought I'd check to see if it was just something I hadn't come across before...
Thanks,

Hello,
I'm not sure if this is the right forum for this, but I'll bludgeon on regardless until somebody says stop :)
I've been handed a "state transition" table for a finite state machine based on JK Flip-Flops and the associated Karnaugh maps generated from it. Each of the k-maps has an...
Hello,
again, many thanks for all the help here and the very useful links.
If somebody could answer a few more questions for me, that would be very helpful and much appreciated;
Does regenerative braking only take place if the armature windings of the motor in question are reversed...
Thanks very much for your help - I have to admit, I did try reading up on this on google before coming here, but I felt none-the-wiser for what I found :(
Thanks for the link and the explanation - it;s very much appreciated :)

First, thanks very much for your replies and patience with me here :)
Current maintaining the same direction and voltage changing polarity seems contrary to how I understand A.C. Conventional current must surely flow from +ve to -ve at all times?
At 90° phase, the source is at V-peak, isn't...
Do you mean that, if the load is capable of generating power itslef (e.g. a motor) and the firing angle is 90° or more, then for the first 90°, power can be taken from the load and fed back into the supply?
wouldn't the effective supply from the load be blocked by the polarity of the SCRs?

Hello,
can anybody explain to me what the benefit of fully controlled bridge rectifiers are over half-controlled bridge rectifiers, please?
It seems to me that their output is the same and that the triggering arrangement of a fully-controlled bridge is more complex than for a...
