**circuit with an uncharged capacitor -- desperate**

## Homework Statement

http://img91.imageshack.us/img91/7533/physicsimage.gif [Broken]

Switch S has been open for a long time. It is closed suddenly at t=0.

A long time later, it is opened.

Determine the potential across and the current through each component at the following times.

**Immediately after S closes.**<-- one i don't understand...

A long time after S closes.

Immediately after S is reopened.

## Homework Equations

Q=CV

## The Attempt at a Solution

So immediately after S closes, the capacitor charge is neutral, right? (Since it is uncharged.) The solution says that the current will not go through Resister 2.

So I do not understand why the current will not go through Resistor 2 and go through Capacitor instead.

I thought current charges cannot jump to the other side of the capacitor...

There is potential difference between battery, so I thought the current will try to go through resister 2 due to the emf of the battery...

But that is not the case.

I am wondering why all currents going to R2 and C is used to charge the capacitor...

and i also do not understand why that results in no current through R2...

Thank you SO much in advance.

I am sso stuck and very desperate...

If you cannot answer all my questions, my biggest most important question is... Why does current NOT go through R2?

Again, thanks so much for your time.
