LOL, I'm having a conversation with myself... Anyways, since the gate is insulated from the other terminals, gate current is zero. Thus my previous explanation about how a large current can be formed due to gate current is so blatantly wrong. D'oh! *make note to self: "don't quit your day job"*...

Oh wait, I've just read an explanation on its amplification ability but I stilll don't get it. Using, the same circuit, if GS has a small varying voltage, a large varying current flows bewteen the source and drain. This current flows through the drain resistor,across which an amplified version...

Hi, just logged on first time in ages. Got a message saying that my password was 563 days old lol. Right now, I'm in first year of uni so very stupid :smile: Anyways, we're studying about field-effect transistors. I understand how the gate controls the current via adjusting the size of the...

Thanks very much. Yeah, it clicked. Stupid me :)

Hi, I have a question concerning the attached diagram: The question which accompanied the diagram is: Why does the aluminium rod (the one that lies across the other two) slow down when a current is produced? The official answer is: "A current is produced in the rod which experiences a force...

Cool. I'll get to it.

Thanks. Yeah I saw those before when I searched but I thought they were just illustrations. I had hoped that there was a shortcut way...seems like i have to stop being lazy and 'just do it' :frown: Once again, thanks for the help. :smile: I'm not :confused: anymore.

Thanks for the quick reply. I think i wasn't specific enough. I do graphics and design at school and I am designing a device that includes the worm gear. I know what the gear looks like but I need to know the visual representation of it since I have to draw some formal instrumental of the machine.

Oh oh. I just realize that i should post this in the educational section. I am sorry! Is there an administrator that can move this thread there?

This is my first post Sorry that it has to be such a stupid question... How does one draw a worm gear along with its worm wheel? I know that a worm gear is made up of a helix but I sure hope that I do not have to draw that! Is there a much simpler representation?
