 1 . In an RC circuit, the capacitance causes a between the voltage and current that depends on the relative values of the resistance and capacitive reactance. [Hint] 2 . In an RC circuit, the resistor voltage and current lead the source voltage, and the capacitor voltage the source voltage. [Hint] 3 . A produces sine waves, pulse waveforms, or triangular (ramp) waveforms. [Hint] 4 . The of an RC circuit is the total opposition to sinusoidal current. [Hint] 5 . In a purely capacitive circuit, the impedance is equal to the total capacitive . [Hint] 6 . In an impedance , the length of each phasor represents the magnitude in ohms, and the angle is the phase angle of the RC circuit and represents the phase difference between the applied voltage and the current. [Hint] 7 . In a series circuit, the is the same through both the resistor and the capacitor. [Hint] 8 . In an RC circuit, Z is dependent on frequency. [Hint] 9 . Capacitive is the ability of a capacitor to permit current. [Hint] 10 . The is the unit of capacitive susceptance. [Hint] 11 . In a purely ac circuit, all of the energy delivered by the source is dissipated in the form of heat by the resistance. [Hint] 12 . In a purely capacitive ac circuit there is no net energy . [Hint] 13 . When there is both resistance and capacitance in an ac circuit, some of the energy is alternately and returned by the capacitance and some is dissipated by the resistance. [Hint] 14 . The phasor combination of resistive power (true power) and reactive power is known as power. [Hint] 15 . The power is the relationship between volt-amperes and true power or watts. [Hint] 16 . The power factor can vary from 0 for a purely reactive circuit to for a purely resistive circuit. (Note: Use number answer.) [Hint] 17 . The RC network is a phase circuit in which the output voltage leads the input voltage by a specified amount. [Hint] 18 . are frequency-selective circuits that permit signals of certain frequencies to pass from the input to the output while blocking all others. [Hint] 19 . A -pass filter is a certain type of filter whereby lower frequencies are passed and higher frequencies are rejected. [Hint] 20 . A -pass filter is a certain type of filter whereby higher frequencies are passed and lower frequencies are rejected. [Hint] 21 . Frequency , in electrical circuits, is the variation in the output voltage (or current) over a specified range of frequencies. [Hint] 22 . The frequency is a frequency at which the output voltage of a filter is 70.7% of the maximum output voltage. [Hint] 23 . is the application of a dc voltage to an electronic device to produce a desired mode of operation. [Hint] 24 . is the range of frequencies that is considered to be passed by a filter. [Hint] 25 . In an RC circuit, if the resistor , the capacitor will not charge. [Hint]
