I was given this problem throught WebAssign for my physics class: I am given an image of a power supply, followed by a circuit, a resistor1, then it breaks in two paths, one leading to another resistor2 and the other leading to a capacitor and then another resistor3, then the two paths come together and meet back at the power supply. For each of these I am given the values: R1=13000 [itex]\Omega[/itex] R2=18000 [itex]\Omega[/itex] R3=2000 [itex]\Omega[/itex] dV=8.1 V Capacitor=1.0E-5 F The first part of the question asked for me to find the current in each of the resistors, which was fairly simple. To do this, I used the formula: I=V/R to get 261 [itex]\mu[/itex]A for the first and second resistors, and 0 for the thirds, as when the switch was thrown, the capacitor had to charge and no current reached that resistor. Now, I am completely lost as to how to find the charge on the capacitor. I have searched for methods, and have only managed to confuse myself even more. I do not know what formula to use. If I did, this would be much, much easier. Can anyone help me? Attached is a file containing the exact problem copied to microsoft word. Any assistance you can offer will be greatly appreciated!
