Hello,

I've just learned about the basics of circuits but then my teacher gives us a take home problem that contains resistors and capacitors...

On top of that, the problem also involves using specific seconds to measure the values we need.

I don't know if I missed a day for the notes on this, but I have absolutely no idea how to do this!

The circuit can be found here:

Help with just this one question would be awesome and then maybe I can get the rest!

"... At t = 0s switch one (1) is closed but switch three (3) remains open

a) What current flows through the fifteen (15) resistor at 0 seconds?

b) At 10 seconds what voltage will have built up on the 6 micro farad capacitor?"

Thanks!

EDIT: Oh, and my attempt was to just put it in Multisim and see what happened, getting:

a) 6 Amps

b) 60 Volts

Again, don't know why because I don't understand why there's certain times in the problem...
