I am trying to do these 2 problems. I'm starting out with the RC Circuit (2nd one):
h t t p ://img201.imageshack.us/my.php?image=circuit5ij7.png
*delete spaces or link won't load!
a) The capacitor acts as a bare wire with no resistance, so:
I=V/R=V/(4/5R)
b) Capacitor acts as an open circuit, so:
I=V/R=V/(4R)
Are those right so far?
I need a little help on c, d, and e.
What were the questions? What is the circuit?
A capacitor acts as an open circuit to DC, but has no resistance.
The questions is in the link I gave above. Here it is again (you have to delete the spaces in 'h t t p :'):

Sorry, I forgot to check out the link with the circuit and the questions. That was clever of you to add the spaces in h t t p so the URL could be displayed.
(a) Initially, C looks like zero resistance, so the effective resistance seen but the battery is 4R/5
(b) steady state I = V/R, since the capacitor cannot allow DC current
(c) current = 0 through the battery, but V/(5R) through 4R, and the capacitor discharges.
(d) Solve exp[-t/(5RC)] = 0.5 , for t.
5RC is the series resistance that the capacitor sees while discharging
(e) (1/2) C V^2 is the energy dissipated in resistors while discharging
To determine if your answers for (a) and (b) are correct, we need some additional information. Specifically, we need to know the values of V, R, and 4R in order to calculate the currents (I) correctly. Additionally, please clarify whether you are assuming an AC or DC circuit to provide a more accurate response.
For problem (c), we need to find the time constant (τ) of the RC Circuit. The time constant represents the time it takes for the voltage across the capacitor to reach approximately 63.2% of its maximum value when either charging or discharging. The formula for the time constant is given as τ = R * C, where R is the resistance and C is the capacitance.
To solve problem (d), we need additional information. Please provide any given values or further instructions related to this problem, so we can guide you properly.
Similarly, for problem (e), we need more information to provide specific guidance on how to solve the problem. Please provide any given values or further instructions related to this problem.
Once we have the necessary information for (c), (d), and (e), we can provide detailed explanations on how to approach and solve these problems.
