Homework Statement The switch in the RC circuit shown in the figure is closed at t=0. What is the charge on the capacitor at the time t = .35 ms? I'm 95% sure I'm using the right formula but it's not working so I was wondering if I was possibly confusing something? Homework...

Homework Statement Alrighty, my question is the exact same one that is written in this post - https://www.physicsforums.com/showthread.php?t=528337 The issue I'm having is understanding how to make/write my equations. I guess I just don't understand how you can know which way the current goes...

Homework Statement http://tinypic.com/r/e8v1ad/6 ^^ that is a photo of the circuit Homework Equations P = I*V , but i don't understand how to do it with two loops and two batteries like in this photo. The Attempt at a Solution I have calculated I1 to be .9, I 2 to be .15 and...

It worked out perfectly :) thanks

And was I doing B on the right track than? just my numbers were messed up?

..so would A) equal 3.3 uF then?

UGHH i totally see what i did. dangit i was doing 1/3 + 1/6 = .5 but I am pretty sure its suposed to be 1/3 + 1/6 = 1/x ----> which would make the combination of the top to uF equal 2 instead

Homework Statement the question - http://tinypic.com/r/14l37yv/6 its a little hard to see but the top left capacitor is 3 uF, the one to its right *(in series) is 6 uF, the one on the bottom left is 2 uF, the one in series with the 2uF one is 4 uF and on the bottom is 90V. Homework Equations...
