Question

Rev You have a 250- resistor and a 0.450-H inductor. Suppose you take the resistor and inductor and make a series circut with a voltage source that has a votage amplitude of 35.0 V and an angular frequency of 230 rad/s Part A What is the impedance of the circult? 180 AEDO ? Submit Part 8 What is the current amplitude? %AED RO? Submit Request Answer

Answer 1

a)

impedance

Z^2 = R^2 + ( wL) ^2

Z = 270.58 ohm

====

current

i = V/Z = 35 / 270.58 = 0.13 A

====

c)

Vr = 0.13* 250 = 32.5 V

d)

VL = 0.13* 230* 0.45 = 13.455 V

e)

phi = arctan ( wL / R) = arctan ( 230* 0.45 / 250)

phi = 22.49 deg
