- Three capacitors having capacitance values of 20F,40F, and 50F are connected in parallel to a 60 - Hz power line. An ammeter indicates a circuit current of 8.6 amperes. How much current is flowing through the 40F capacitor?A series RL circuit consisting of a single resistor a single inductor is being supplied by a 20 volt battery. The circuit is currently open and has a initial current of 0 A. The resistor has a resistance value of 100 ahms. If the current flowing through the circuit 1.5 sec after closing the circuit is 0.15 A, find the value of inductanceHow can four 100 kΩ resistors be connected so that the equivalent resistance of the four equals 250 kΩ? Sketch the arrangement, describe the resistor arrangement in words, and justify your picture by calculating the equivalent resistance.

- An inductor of 5H, a resistor of 20ohms, and a capacitor of 20mF are connected in series with a source of E=10cos2t V. At t=0, the charge on the capacitor and current in the circuit is zero. Find the charge and current at any time t.The circuit shown in the attached image contains a voltage source with emf ε = 2.99 V, a resistor with resistance R = 135 kΩ, and a capacitor with capacitance C = 612 nF. When switch S is set to position a, the three circuit elements are in series. When the switch is in position b, the battery is excluded from the circuit. The switch is initially moved to position a, where it remains for a sufficiently long time that the capacitor is fully charged. The switch is now moved to position b. What is the magnitude of the instantaneous current, in amperes, through the resistor the instant the switch makes contact with terminal b? With time meausred the instant that switch S is closed in position b, calculate the time, in seconds, when the charge on the capacitor is one-half of its maximum value. Calculate the current through the resistor, in amperes, at time t = 155.5 ms after the switch is closed in position b.To what circuit element does a very large (ideally, infinite) inductance having an initial current of 10 A correspond? Explain your answer.
- Determine the equivalent capacitance of each of the circuits in the figure shown. Note: I leave the image of the exercises in Spanish, but it is easy to understand. Also in the other image is the correct final answer, for checking. IMPORTANT:Please, preferably the procedure should be digital, not on paper.This way I understand better.I would appreciate it very much!For this problem, there is no initial energy present in the system, and you may assume the passive sign convention. The voltage across a 27mH inductor is given by the function below. What is the current through the inductor a very long time after t=10 seconds? Express your answer to the nearest 0.01 Ampere, but do not enter the unit. v(t)=100 δ(t-10)mV.( need only handwritten solution .otherwise downvote.)In this circuit, the capacitance of the capacitor is 1 F, the resistance of the resistor is 1 Ohm, and the battery voltage = 1 V.

Also in the other image is the correct final answer, for checking.Referring to the circuit in the figure shown, calculate the value of R that will make the energy stored in the capactior equal to that stored in the capacitor equal to that stored in the inductor under dc conditions. Note:In the attached images, the exercise is in Spanish and is easier to understand. There is also the final correct answer, to check the answer.A 1-H inductor is connected in series with a 6-ohm resistor. If the connection is energized from a 9-V DC source, determine the current (in amperes) through the circuit for a long time. The initial current is 100 mA.
