- 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.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?A pure capacitive circuit is connected to a 480-volt, 60-Hz power source. An ammeter indicates a current flow of 24 amperes. The circuit current must be reduced to 16 amperes by connecting a second capacitor in series with the first. What is the value of the existing capacitor? What value capacitor should be connected in series with the original capacitor to limit the circuit current to 16 amperes?
- A 15-F AC capacitor is connected in series with a 50 resistor. The capacitor has a voltage rating of 600 WVDC. The capacitor and resistor are connected to a 480-V, 60-Hz circuit. Is the voltage rating of the capacitor sufficient for this connection?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?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?

The student does have an electrometer (an ultrahigh impedance voltage meter that will change the charge on a capacitor by a negligible amount), a precision C1 = 1 μF capacitor, and a 10.5 V voltage source. --> The student discharges C1 and charges C2 to 10.5 V. When the student removes C2 from the voltage source and connects C1 in parallel, she measures the voltage across each to be 6.3 V. What is the value of C2, in microfarads? b.What is VL,max(closed) and VL,max(open), the magnitude of the maximum voltage across the inductor during the time when the switch is closed? A circuit is constructed with four resistors, one inductor, one battery and a switch as shown. The values for the resistors are: R1 = R2 = 46 Ω, R3 = 92 Ω and R4 = 113 Ω. The inductance is L = 296 mH and the battery voltage is V = 12 V. The positive terminal of the battery is indicated with a + sign.
- Please help me, thank you so much. I have underlined what I thought the answer was. The questions are as follows: The switch in the following circuit closes at t = 0 (assume no initial charge on the capacitor). Determine the voltage, vC(t), and the current, iC(t), prior to the switch closing for t = 0‒ Vc(0-)= 0V because the initial charge is 0 Ic(0-)= 0mA because there is no power supply Determine the vC(t) and iC(t) after the switch closes and after a long time (i.e. t = 0+ and t = ∞). Vc(0+)= 0V because the capacitor doesn’t charge instantaneously but increases exponentially. Ic(0+)= Current shoots up to 3.75 mAmps when the switch is closed. Vc(infinity) = asymptotic limit of 637 volts after increasing exponentially. Ic(infinity) = 0 mA after decreasing exponentially Determine the time constant, τ, for t > 0. τ=RC = (0.25uF)*(25.5k ohms) = 0.0063 Write out the equations for the voltage, vC(t), and the current, iC(t), for t > 0. Vc(t)=…Find the voltage across the terminals of the capacitors in the circuit shown in the figure under dc (direct current) conditions.
