Does the resistance in the secondary circuit connected to a transformer provide for a certain resistance in the primary circuit?
Sorry about asking again, but I want to be clear that we are talking about the same thing: did you get the value of 2 ohms as the net resistance from the book? I could tell that the power and stepped-up voltage were probably given values, but I was wondering about the resistance.I actually took those values from a book...
but from your last sentence, it came to thought that if there was resistance in the primary, it would also affect the secondary...and I would have to take that into account. But I was just wondering: If I1*V1 = I2*V2 in an ideal step up transformer and since V2 is larger than V1, then I2 would have to decrease to compensate. In Ohm's relation, if V increases, so should I, which is sort of opposite of what happens here. This is pretty much where the root of my confusion holds...because of this, I'm not sure how effective Ohm's relations are, even though they are used to derive several of the transformer equations.
