Reactance in general is NOT a function of, a. frequency b. amplitude c. phase d. resistivity e. none of these 11. A capacitor generally passes ______ and suppresses _______. a. big amplitude, small amplitude b. high frequency, low frequency c. small amplitude, big amplitude d. low frequency, high frequency e. none of these 12 The concept of impedance can be applied, a. all types of AC signals b. only sinusoidal signals c. square wave signals d. only for DC signals e. none of these 22. A resistor and capacitor are in series with an AC current flowing through them. The peak voltages across the resistor and capacitor are 3 and 4 volts respectively. What is the peak voltage across the combination? a. 1 b. 2.65 c. 5 d. 7 e. none of these

Explanation / Answer

1)Phasors are quantities which can be

a. added

2)Reactance in general is NOT a function

e. none of these

3) high frequency, low frequency

4)all types of AC signals

5)since both are in series so will add up the voltage

Vpeak=3+4

=7volts
