- 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?You are working in an industrial plant. You have been instructed to double the capacitance connected to a machine. The markings on the capacitor, however, are not visible. The capacitor is connected to 560 volts and an ammeter indicates a current of 6 amperes flowing to the capacitor. What size capacitor should be connected in parallel with the existing capacitor? What is the minimum AC voltage rating of the new capacitor? What is the minimum DC voltage rating of the new capacitor? What is the minimum KVAR size that can be used in this installation?You are an electrician working in an industrial plant. You discover that the problem with a certain machine is a defective capacitor. The capacitor is connected to a 240-volt AC circuit. The information on the capacitor reveals that it has a capacitance value of 10 mF and a voltage rating of 240 VAC. The only 10-mF AC capacitor in the storeroom is marked with a voltage rating of 350 WVDC. Can this capacitor be used to replace the defective capacitor? Explain your answer.

A dielectric material is inserted between the plates without changing the spacing, and the capacitance becomes 15 F. What is the dielectric constant of this material?You are a journeyman electrician working in an industrial plant. Your task is to connect an inductor to a 480-V, 60-Hz line. To determine the proper conductor and fuse size for this installation, you need to know the amount of current the inductor will draw from the line. The nameplate on the inductor indicates that it has an inductance of 0.1 H. An ohmmeter reveals that it has a wire resistance of 10 . How much current should this inductor draw when connected to the line?
- A postage stamp mica capacitor has the following color marks starting at the upper left dot: yellow, violet, brown, green, no color, and blue. What are the capacitance value, tolerance, and voltage rating of this capacitor?You find that a 25-F capacitor connected to 480 VAC is defective. The storeroom has no capacitors with a 480-VAC rating. However, you find two capacitors rated at 50 F and 370 VAC. Can these two capacitors be connected in such a manner that they can replace the defective capacitor? If yes, explain how they are connected and why the capacitors will not be damaged by the lower voltage rating. If no, explain why they cannot be used without damaging the capacitor.Describe the behavior of the following circuit under the following scenario: (1) Begin with switch S1 open, (2) close switch S1 long enough till the voltage across the inductor is almost zero, and then (3) open switch S1 for a long time beginning at time t = 0.
- Design a single circuit element containing one inductor, one capacitor and one resistor with v(t)=-3e-3tV and i(t)=4+2e-3tA for t>0. Also specify the value of the inductance, capacitance and the resistance of the three element.An RC circuit (see Figure 4) contains a resistor (10 ohms) anda capacitor (0.2 F) linked in series with an electromotiveforce E(t) = 10 sin 2πt.(a) Use a numerical solver to sketch the graph of thecharge on the capacitor versus time for each of theinitial conditions Q(0) = −1, −0.75, −0.5,..., 1 onthe time interval [0, 15]. What appears to happen toeach of the solutions with the passage of time? Explain what might be meant by a steady-state response.(b) What is the frequency of the emf? What appears to bethe frequency of the steady-state response? Hint: Recall that in the function f (t) = sin ωt, ω is called theangular frequency, the period is given by T = 2π/ω,and the frequency is the reciprocal of the period.Think of the frequency as the number of cycles persecond, a unit known as Hertz (Hz).All capacitors were initially discharged. at t = 0, S1 is placed at position 1 and S2 is closed.
