Ohh okay I get it. They all reach maximal points at different times, so I'm calculating each component's maximal voltage drop? Still, it wouldn't make sense for the inductor to have a maximal voltage that goes over 50 Volts.

I got around 105 V when I add the components. As for the phase shift, I guess I didn't, but I'm not entirely sure what you mean by that.

Homework Statement A circuit contains a 100Ω resistor, a .0500H inductor, a .400μF capacitor, and a source of time-varying emf connected in series. The time-varying emf is 50.0 V at a frequency of 2000 Hz. a) Determine the current in the circuit. b) Determine the voltage drop across...

Oh sorry, that was the right equation. I'm bad at formatting so that's why I said x-hat and z-hat. And it's the magnetic field equation that's really throwing me off. I don't understand what xz-hat and zx-hat (again, sorry with the formatting but I can't seem to find the proper unit vector...

This is what I have so far now. For torque, I have the equation \tau = NiABsin\Theta. Since there is only one loop, N would be 1. And since \tau = F x r, I can equate the two expressions and solve for F. But I'm still confused with what to do. Do I have to find the torque for each side...

Homework Statement A square loop of wire of side length L lies in the xy-plane, with its center at the origin and its sides parallel to the x- and y- axes. It carries a current i, in a counterclockwise direction, as viewed looking down the z-axis from the positive direction. The loop is in...

That makes sense. Thanks for the help everybody!

Since r is an arbitrary length that is less than r1, how would we determine what the charge would be?

So it would have to be 3kQ/(r2) then.

Oops, that should be R2 haha. So my answers were correct then? And also, if both the sphere and the shell were insulators, would the answers be the opposite? Like for r < r1, the answer would be 3kQ/(r12)?

Homework Statement A solid conducting sphere of radius r1 has a total charge of +3Q. It is placed inside (and concentric with) a conducting spherical shell of inner radius r2 and outer radius r3. Find the electric field in these regions: r < r1 r1 < r < r2 r2 < r < r3 r > r3...
