In a standard RLC circuit that we are looking at R = 0.075 Ω , L = 1.2 H and C = 1.6 F. The initial charge carries by the capacitor is Q0 = 0.045 C. The switch is closed at time t = 0. Calculate the value of Q, in coulombs, at time t = 1s.
Consider the circuit shown. Before the switch is closed, both capacitors are uncharged. V = 12.0 V, R1 = 90.0 Ω, R2 = 30.0 Ω, R3 = 60.0 Ω, C1 = 5.00 uf, C2 = 3.00 uf. Immediately after he switch is closed, what is the current in the circuit.
In the figure, suppose the switch has been closed for a length of time sufficiently long for the capacitor to become fully charged. For this circuit, R1 = 12.0 kΩ, R2 = 15.0 kΩ, R3 = 3.000 kΩ, C = 10.0 μF , and emf = 9.00 V. Find (d) the potential differance across R2. (e) the charge on the capacitor.

For the circuit shown below, =20V , L = 4.0 mH, and R = 5.0 . After steady state is reached with S1 closed and S2 open, S2 is closed and immediately thereafter (at t = 0) S1 is opened. Determine (a) the current through L at t = 0, (b) the current through L at r = 4.0 x 10-4 s, and (c) the voltages across L and R at t = 4.0 x 10-4 s.
In Figure 33.9A (page 1052), the switch is closed at a at t = 0. Find an expression for the power dissipated by the resistor as a function of time, and sketch your result. Is the power lost greater as soon as the switch is closed or a long time after it has been closed? Does your answer make sense?
Review. The use of superconductors has been proposed for power transmission lines. A single coaxial cable (Fig. P23.73) could carry a power of 1.00 103 MW (the output of a large power plant) at 200 kV, DC, over a distance of 1.00 103 km without loss. An inner wire of radius a = 2.00 cm, made from the superconductor Nb3Sn, carries the current I in one direction. A surrounding superconducting cylinder of radius b = 5.00 cm would carry the return current I. In such a system, what is the magnetic field (a) at the surface of the inner conductor and (b) at the inner surface of the outer conductor? (c) How much energy would be stored in the magnetic field in the space between the conductors in a 1.00 103 km superconducting line? (d) What is the pressure exerted on the outer conductor due to the current in the inner conductor? Figure. P23.73
A man foolishly tries to fish a burning piece of bread from a toaster with a metal butter knife and comes into contact with 120-V ac. He does not even feel it since, luckily, he is wearing rubber-soled shoes. What is the minimum resistance of the path tire current follows through the person?
Figure P18.37 shows a simplified model of a cardiac defibrillator, a device used to patients in ventricular fibrillation. When the switch S is toggled to the left, the capacitor C charges through the resistor R .When the switch is toggled to the right, the capacitor discharges current through the patients torso, modeled as the resistor Rtorso, allowing the hearts normal rhythm to be reestablished. (a) If the capacitor is initially uncharged with C = 8.00 F and = 1250 V, find the value of R required to charge the capacitor to a voltage of 775 V in 1.50 s. (b) If the capacitor is then discharged across the patients torso with, Rtorso = 1250 , calculate the voltage across the capacitor after 5.00 ms. Figure P18.37
