The equations look OK to me. If the reactive load is capacitive, then the reactive power will be negative. If you substitute an inductor for the capacitor, then the reactive load will be positive.

What do you know about resolving forces in 2 dimensions?

Why don't you take the known information and put it on a graph. It's a start.

commutator?

It would help if you provided a diagram with the various resistances labelled. I remember seeing a Varley bridge many years ago, but I don't remember the basic circuitry and how it is connected to cable.

Area of electrode = pi * d^2 /4 Looks like you used pi * d^2

Yes, Zin should be in ohms.

The part (c) result matches what I came up with. You have a delta configuration to start, with the capacitance from a to b across the top. The left leg of the delta is an L-R combination. The right leg is an L-C combo. For the L-R combo, I got a value of 2 + j4. For the L-C combo, I got a...

Why don't you first show us how you came up with your results?

You need to try something to see if you are on the right track. We can't just give you the solution. What do you know about Fourier or Laplace transforms?

It would help things if you first produced a clearer circuit diagram.

A represents the area of one rectangle. You have 4.

Under your step 1a, you had A = wl Under step, 1b, you have 4A = wl. Obviously, it should be 4A = 4wl OK?

I think you started out OK with the 0.6 PF portion except that what you call Xc is actual inductive or Xl. Nonetheless, your Z1 reflects this result. I like to keep a circuit diagram in mind, like the following I also like to work with the power quantities rather than impedances. So you...

I don't think the problem has been adequately described yet to suggest what the remedies ought to be. You are asking a bunch of people who are remote from your customer's location so we're depending on you to be our eyes and ears. How big is the office building? 1 floor, 2 floors, 3 . . . I...
