1:39 PM webassign.net ·'11 Verizon When only a resistor is connected across the terminals of an ac generator (103 V) that has a fixed frequency, there is a current of 0.535 A in the resistor. When only an inductor is connected across the terminals of this same generator, there is a current of 0.436 A in the inductor. When both the resistor and the inductor are connected in series between the terminals of this generator, calculate the following. (a) the impedance of the series combination (b) the phase angle between the current and the voltage of the Additional Materials Section 233 A 2200- resistor and a 1.6-uF capacitor are connected in series across a generator (60.0 Hz, 120 V rms). Determine the average power delivered to the circuit. Additional Materials a Seotion 233 A generator is connected to a resistor and a 0.031-H inductor in series. The rms voltage across the generator is 8.3 V. When the generator frequency is set to 121 Hz, the rms voltage across the inductor is 2.9 V. Determine the resistance of the resistor in this circuit. Additional Materials Section 233 A series RCL circuit has a resonant frequency of 740 kHz. If the value of the capacitance is 2.10 109 F, what is the value of the inductance?

At resonant frequency

XL = Xc

w*L = 1/(w*C)

w = 2*pi*f

L = 1/(4*pi^2*f^2*C)

Using given values:

L = 1/(4*pi^2*(740*10^3)^2*2.1*10^-9)

L = 2.2*10^-5 H
