Admittance is only useful in series circuits. the phasor current divided by the phasor voltage. the phasor voltage divided by the phasor current. None of the above. If two sine waves are in phase, then they have a phase angle of: 180 degrees 90 degrees 0 degrees 45 degrees Test equipment that has the ability either square, triangular, or sawtooth waveform is called: a radio frequency generator an audio frequency generator a function generator a frequency meter or counter. As a capacitor is being charged, current flowing into the capacitor will: increase decrease remain the same cannot tell If the distance between the plates or a capacitor is increased, then its capacitance will: increase decrease remain the same cannot tell The material used in between the plates of a capacitor is called the dielectric. True False Which one of the following capacitors is considered polarity sensitive? electrolytic mica proper ceramic A capacitor charges to which percent of its maximum value in one time constant? 3.14 86 70.7 63.3 Power that is stored from the source and then returned to the source is called: reactive power impedance power apparent power true power Power that is measured in volt-amperes is called: true power reactive power apparent power impedance power If a series ac circuit is equally resistive (R) and capacitive (C), then angle theta must equal: -45 degrees -90 degrees 90 degrees 45 degrees What filter action is gained from a resistor and a capacitor connected in series if an ac signal is the input, while the output is across the capacitor? band stop low pass band pass high pass
8) admittance is defined as ratio of The phasor current divided by phasor voltage so
option B
9) if two sine waves are in phase then phase angel between them is 0 degrees.
option C
10) the test equipment which has ability to produce square triangular or saw tooth wave is Function generator
option C
11) as a capacitor is being charged current flowing into the capacitor will Decreases
option B
12) if the distance between the plates of capacitor is increased then capacitance will Decrease
option B
13) the material used in between the plates of a capacitor is called as Dielectric medium
option A
14) Alectrolytic type of capacitors are polarity sensitive
option A
16) Power stored from the source and then returned to the source is called Reactive power
option A
17) power measured in volt -ampere is called Apparent power
option C
18) in a series ac ckt with R = Xc then angle between them theta is -45 degrees
option A
19) low pass filter is the action
low pass RC filter is simply an RC series circuit across the input, with the output taken across the capacitor
option B
