Question 6 In a phasor diagram diagram of an RLC circuit, the magnitude of the sum of the instantaneous voltage phasors for the inductor, resistor, and capacitor must always add up to the max emf of the AC source. True False Question 7 On a phasor diagram of an AC circuit, the phasor for the voltage across the resistor always points in the same direction as the current phasor. True False Question 8 In a phasor diagram for an RLC circuit, the voltage phasors for the inductor and capacitor always point opposite each other and are always perpendicular to the voltage phasor for the resistor. True False Question 9 For circuits with either an inductor and/or a capacitor, the current gets out of phase with the voltage. For these circuits how are the frequencies of the current and voltage related? Question 10 The reactance of a capacitor is 7.0 MI at a frequency of 0.30 kHz. What is the capacitance? 0.48 muf 0.107 muF 0.076 muF 3.0 muF

Explanation / Answer

6) True ,since Sum of instantaneous Voltages is

VR+VL+VC=V

7)

True

8)

True

9)

Frequecny would remain same

10)

Capacitive reactance

XC=1/2pifC

=>C=1/2pi*f*XC =1/2pi*300*7000

C=7.57*10-8=0.076 uF
