RC Circuits A capacitor with 150Ω of capacitive reactance is across an ac source. The impedance, expressed in polar form, is Z = 150 angle 180° Ω Z = 150 –90° Ω Z = 150 Z = 150 angle – 90° Ω Z = 150 angle 180° Ω Z = 150 –90° Ω Z = 150 Z = 150 angle – 90° Ω ANSWER DOWNLOAD EXAMIANS APP
RC Circuits In a series RC circuit, when the frequency and the resistance are halved, the impedance is halved cannot be determined without values is reduced to one-fourth doubles is halved cannot be determined without values is reduced to one-fourth doubles ANSWER DOWNLOAD EXAMIANS APP
RC Circuits A 47Ω resistor and a capacitor with 150Ω of capacitive reactance are in series across an ac source. The impedance, expressed in rectangular form, is Z = 47Ω + j150Ω Z = 197Ω Z = 103Ω Z = 47Ω – j150Ω Z = 47Ω + j150Ω Z = 197Ω Z = 103Ω Z = 47Ω – j150Ω ANSWER DOWNLOAD EXAMIANS APP
