15. If a non-electrolytic capacitor with a maximum voltage rating of 100v is connected to an AC signal, what is the largest RMS voltage that can be used?

3- Please I want answer of this Electrical Principles question. Thanks

Okay for   Determine the mathematical expression for the voltage vC and the current iC for the discharge phase. I got Vc = 8e-t/0.2s V and iC = -4e-t/0.2mA But I need help with the last question Plot the waveforms of vC and iC for a period of time extending from 0to 2 s from when the switch was thrown into position 1.

b) Determine the voltage ?(?) and current ?(?) sinusoidal forms. Sketch one cycle of the waveforms in the same x-axis. Clearly indicating the peak value and the period of each waveform and the phase difference (in milliseconds) between the two waveforms. c) Determine the values of resistance R and inductance L. d) Determine the phasors ?L, ?r and ?c. e) Sketch the phasor diagram showing ?s, ?r, ?r, ?c and ?.

What is the result of increasing the frequency of the applied voltage to a capacitor? A. Decreased capacitive reactance. B. Decreased current flow. C. Increased capacitive reactance. D. Increased voltage. 9.

10 V sine 90 kHz 1 kQ C1 1 nF 2. Using a Square function with 90,000 Hz in your function-generator, a 1000-ohm resistor, and a 1 nano-Farad capacitor, determine the charging time for the capacitor. Show your calculations and show the charging-discharge curve with an oscilloscope in TINKERCAD.

Three 20uF capacitors are connected in series with each other. A 1k ohm resistor and an LED connected in series to each other as well, but branched in parallel to all three capacitors. How long would the LED stay lit after power is removed? What current would flow through it during the charge cycle if VT=9v?

A resistor R and a capacitor C are connected in series across a 400 V variable ac supply. When the frequency is 40 Hz, it draws 10 A current, and when the frequency is 50 Hz, it draws 15 A current. Find R and C.

A sinusoidal voltage has a value of 100 volts at 2.5 milliseconds and takes 20 milliseconds to complete one cycle. Then find the maximum cost and the time to reach it for the first time.

Do we need to take into account the internal resistance of the voltmeter when discharging the capacitor?  Why or why not?
