    Damped Oscillations in an RLC circuit

    would the time it takes be equal to 5 times the period, so 10pi/w?

    Damped Oscillations in an RLC circuit

    Homework Statement A single loop circuit consists of a 7.2 ohm resistor, a 11.9 H inductor, and a 3.4*10^-6 F capacitor. Initially the Capacitor has a charge of 6.3*10^-6 C and the current is zero. Find the charge on the capacitor N complete cycles later for N=5.Homework Equations 2. Homework...

    Energy Dissipation in an RC Circuit: Finding the Total Thermal Energy

    oh, and for your question there, I believe resistance affects the time constant RC which affects the rate of the capacitor's discharging.

    Energy Dissipation in an RC Circuit: Finding the Total Thermal Energy

    (it was actually part d. my bad!) A capacitor C=8.00*10^-8F which has an initial charge q=1.4*10^-6C starts to discharge through a resistor R=3.00*10^6Ω at time t=0. Determine the following: a. (3points) the time constant (tau) of the circuit. b. (5points) the current i at t=(tau) c...

    Energy Dissipation in an RC Circuit: Finding the Total Thermal Energy

    yes, thank you, it was the whole question, but there were parts before it. This was part e I believe. I was a little skeptical about U=W because this part is worth 7 points, which makes U=W seem too simple.

    Energy Dissipation in an RC Circuit: Finding the Total Thermal Energy

    are you saying all the energy goes to heat so U=W?

    Energy Dissipation in an RC Circuit: Finding the Total Thermal Energy

    Homework Statement A capacitor C=8.00*10^-8F which has an initial charge q=1.4*10^-6C starts to discharge through a resistor R=3.00*10^6Ω at time t=0. Determine the total energy W dissipated as thermal energy in the resistor. Hint: use energy conservation. The Attempt at a Solution I...

    How Do You Calculate the Power Supplied by Batteries A and B?

    So would I in P=IV be I1, since it goes through each battery, and would V be the emf of each battery?

    How Do You Calculate the Power Supplied by Batteries A and B?

    Homework Statement Calculate the power Pa and Pb supplied by batteries A and B respectively (see attached diagram) Homework Equations P=iV, P=i^2R, and P=V^2/R The Attempt at a Solution I already found i1, i2 and i3 to be 5.714, 1.143, and -4.571 respectively. I am...

    Undergrad How Is the Formula PEcos(θ) Derived for Dipoles in a Constant Electric Field?

    I know that the potential energy of a dipole in a constant electric field is P(dot)E=PEcos(θ), but I can't seem to find how they got here; its not in my textbook. If anyone knows why please tell me.
