Caiculat a O Type here to searchExplanation / Answer
a. Vrms = 80V * .707 = 56.56 v
b. Frequency is going to be 95/2 because the equation is V = Vmax * sin(2 f t)
f = 47.5
c, Irms = 0.50 * .707 = 0.3535
d. the reactance is gonna be Vrms = Irms * Xl or Xc
you found the Vrms and Irms so you just divide Vrms by Irms
Reactance = 56.56/0.3535 = 160
e. use the equation Xc = 1/(2 f C) and solve for Capacitance
C = 1/( Xc 2 f)
you just found the Reactance in part d. so
C = 1/ (160*2**47.5) = 2.094 e -5
