I REALLY NEED AN ENGINERRING EXPERT….I HAVE A SECOND CHANCE TO GET THIS ASSIGNMENT CORRECT!

Fundamental Properties of AC Circuits/Lab

Capacitance and Capacitive Reactance

  1. How much charge (Q) is stored in a 5uF capacitor connected across a 70V supply?
  2. How much charge (Q) is stored in a 20uF capacitor connected across a 70V supply?
  3. For a constant supply voltage and an increasing value of capacitance, what is the effect on the amount of charge (Q)? Explain your reasoning.
  4. For a constant supply voltage and a decreasing value of capacitance, what is the effect on the amount of charge (Q)?
  5. For 50kV applied across a 250pF capacitor, what is the stored energy?
  6. For a fixed frequency of f= 200Hz and the values of C below, determine XC:
    1. C = 1.0uF Xc = ?
    2. C = 0.5uF Xc = ?
    3. C = 0.2uF Xc = ?
    4. C = 0.1uF Xc = ?
  7. Determine the following:
    1. XcT for two capacitors in series with the values Xc1 = 300ohms and Xc2 = 400ohms
    2. XcEQ for three capacitors in parallel with the values Xc1 = 100ohms, Xc2 = 400ohms and Xc3 = 200ohms
  8. For the circuits below, determine CEQ and CT respectively: figure 1 figure 2
