    Solenoid Passing through square coil-Finding electric field

    Solenoid Passing through square coil--Finding electric field Homework Statement A very long solenoid with n turns of wire per unit length and radius b carries a current I(t) which decays with time as I(t)=I0e-t/T. The direction of current in the solenoid is as shown below. The solenoid passes...

    Reducing Circuits to Their Simplest Form

    Okay, So I see what your saying. The correct answer would be E. I and IV, unless I've got something wrong out of your explanations...

    Reducing Circuits to Their Simplest Form

    well the resistors on the outer edges of the diamond are in series. You can reduce those to one resistor each. Then you have 3 resistors in parallel which you can reduce...i think

    Simple DC Circuit (That I Can't Solve)

    I was assuming just for the time being because I hadn't solve the equations for I yet. I actually found the current to be 1.43 Amps. So substitute that in for I instead.

    Simple DC Circuit (That I Can't Solve)

    Is it correct to assume that at the top of the branch the potential is 0?

    Another DC Circuit (But more complicated with a SWITCH and Capacitor)

    Moving on to part C now. When the switch is closed for a very long time, the capacitor starts discharging through the resistors. After a long time, the voltage across the capacitor becomes equal to the voltage across the 100 Ω resistor. V= IR=(0.05A)(100Ω)=5V

    Another DC Circuit (But more complicated with a SWITCH and Capacitor)

    Oh. Now I see what I was doing wrong. Simple Math error. I = 0.05A

    Another DC Circuit (But more complicated with a SWITCH and Capacitor)

    A lot, 6000. Which, is wrong. I'm asking for your help because I don't understand what I'm doing wrong, ehild.

    Yeah, that's what I meant.

    Another DC Circuit (But more complicated with a SWITCH and Capacitor)

    I solved the top equation and that's what I got. Did I label my currents right?
