RC Circuits A 12 kΩ resistor is in series with a 0.02 μF capacitor across a 1.2 kHz ac source. If the current is expressed in polar form as I = 0.3 angle 0° mA, what is the source voltage expressed in polar form? 411.3 V 45.6 V 0.411 V 4.11 V 411.3 V 45.6 V 0.411 V 4.11 V 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 = 103Ω Z = 47Ω + j150Ω Z = 197Ω Z = 47Ω – j150Ω Z = 103Ω Z = 47Ω + j150Ω Z = 197Ω ANSWER DOWNLOAD EXAMIANS APP
