    Calculating Charge and Voltage in an RC Circuit with a Closed Switch

    The same voltage as the battery :D ? isn't it ?

    Calculating Charge and Voltage in an RC Circuit with a Closed Switch

    Got it :) so when the switch is open ... R1 and C2 have the same potential of the total battery... so .. then If I could get the voltage across R1 and then subtract it from the total voltage I will get the voltage on C2 correct ??

    Calculating Charge and Voltage in an RC Circuit with a Closed Switch

    but the caps are fully charged .. so the charges flows to R1 then to the switch then down to R2 and then go back to the battery .. ??

    Calculating Charge and Voltage in an RC Circuit with a Closed Switch

    I have the power at R2 since P = I^2 R2 >> I have P and I have R2 substitute in the equation and I got the current. since P = IV >> I have the current I can get v at R2 because the switch is on and for along time then R1 and R2 are connected in series then I that passes through R2 is the...

    Calculating Charge and Voltage in an RC Circuit with a Closed Switch

    value of V1 = 77.2 Volt and V2 = 134.9 Volt then V of the battery should be V1 + V2 = 212.1 Volt Then I Q1 = C1*Vbattery but it is a wrong answer :S

    Calculating Charge and Voltage in an RC Circuit with a Closed Switch

    Homework Statement Switch S has been closed for a long time, and the electric circuit shown in the figure below carries a constant current. Take C1 = 3.00 µF, C2 = 6.00 µF, R1 = 4.00 k, and R2 = 7.00 k. The power delivered to R2 is 2.60 W. Homework Equations (a) Find the charge on...

    Convergence or Divergence of a Series with Sinusoidal General Term

    Homework Statement an = sum of n * sin(\frac{1}{n} )from n =1 to n =infinity Homework Equations Test the series for convergence or divergence The Attempt at a Solution I tried the comparison test with bn = sum of n but it fails because an < bn which means a series smaller than a divergent...

    Encrypting & Decrypting Text Files with a Key

    Sorry I forgot this. About the waiting in the prompt screen I am sure it isn't waiting for me to put an input or a variable because I am the one who wrote the code and understand when it is asking for input and when it is not... and u can see the code and try it at ur own machine!

    Encrypting & Decrypting Text Files with a Key

    First of all. I am not claiming that I am an engineer. However, I am just using a key !... It might be I am an engineer, doctor, artist..or even a nonsense sentence... And it won't affect the program...! and even if I am claiming that I will be an engineer, u can't judge if I will be a good or...

    Solve Sequence Problem: Prove 0<a<b Implies (n+1)bn > (b n+1 - a n+1)/(b-1)

    Ok I will use ^ and _ ... thank you. concerning to the problem a and b must be integers only not fractions and the minimum value of the n is 1 because an is a sequence

    Solve Sequence Problem: Prove 0<a<b Implies (n+1)bn > (b n+1 - a n+1)/(b-1)

    Homework Statement Let an = ( 1 + \frac{1}{n} )n Homework Equations show that if 0 <= a < b \frac{b n+1 - a n+1}{b-1} < (n+1)bn The Attempt at a Solution I have started from a < b and I said so an < bn Then I multiply by (n+1) So I get the left hand side...
