Variac nonsense

Heres a simple explanation why the contact doesn't interpolate... no doubt you still won't get it. It doesn't involve any math. Voltage A +-----+-----+-----+ | | | | R R R R | | | | V---L1--+--L--+--L--+--L--+---L2---GND V1 V2 How the hell can the voltage A a be any different no matter what L is(the inductance of one turn) and what R is? Your telling me as you move the contact it "interpolates"? So if we move the contact to the left it now somehow interpolates between the voltages? The above is identical to Voltage A +-----+-----+-----+ | | | | R R R R | | | | V---L1--+--L--+--L--+--L--+--L--+--L---L2---GND V1 V2 Where now the contact as moved to the left. It hasn't interpolated between any voltages. It has simply been shifted and the voltage reduced. It would be exactly(almost anyways) the same as if the contact had 20 points of contact or just 1. A is basically The average voltage across the contacts and this average voltage shifts exactly by the same amount as if it were just one point of contact. YOU CAN ONLY CHANGE IN DISCRETE STEPS!!!!. But when you move the contact you do not add any current paths! But it doesn't matter. All the resistors have the high side at the same fucking potential. As you move the contact one turn to the left or right you have increased or decreased that by a constant discrete amount. Each time you do it you move it in a discrete step. There is no damn interpolating. Yet I guess that is even too hard for you to understand? How can the contact be at different potentials? Now for all the fucking genius that believe the contact interpolates heres the fucking reason for a contact - It makes contact wtih more than 1 turn so that the contact will always have a voltage on it. It can't get stuck between two turns and not output a...

I said 'mating line' not 'point contact'. And that certainly IS the way they work.

Why kick a lame dog? Besides, why is my tolerance level any business of yours? JF

Again, you're playing with words. "Mating line" is not an explanation for "the way they work."

You sure do not know a goddamned thing about tangential contact then, dumbfuck John Larkin. The brush face is only flat when it is BRAND NEW. It has an arc (not the spark variety) across the face thereafter. That means that the contact across the face of the winding's wiping area will NOT be anything more than a "mating line" strip of contact that amounts to less than half the width of the brush, you stupid f*ck.

THAT is NOT point contact. THAT IS a "MATING LINE". Do the math, dumbfuck.

Just observing. Be tolerant or not as you choose.
