An LRC circuit consists of a 16.0-μF capacitor, a resistor, and an inductor connected in series across an ac power source of variable frequency that has a voltage amplitude of 21.0 V. You observe that when the power source frequency is adjusted to 49.5 Hz, the rms current through the circuit has its maximum value of 62.0 mA. What will be the rms current irms if you change the frequency of the power source to 60.0 Hz? irms = A

An ac generator has a frequency of 1300 Hz and a constant rms voltage. When a 463-Ω resistor is connected between the terminals of the generator, an average power of 0.260 W is consumed by the resistor.

What is the average power consumed in the inductor–resistor series circuit?

An AC circuit consists of an alternating source potential, a resistor with a resistance 28.7 ohms, an inductor with an inductance 1.27 H, and a capacitor with a capacitance of 736 x 10-6 F.

A capacitor is connected across the terminals of an ac generator that has a frequency of 360 Hz and supplies a voltage of 34 V. When a second capacitor is connected in parallel with the first one, the current from the generator increases by 0.30 A. Find the capacitance of the second capacitor. Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise.

A capacitor (capacitance C₁) is connected across the terminals of an ac generator. Without changing the voltage or frequency of the generator, a second capacitor (capacitance C2) is added in series with the first one. As a result, the current delivered by the generator decreases by a factor of 5.00. Suppose the second capacitor had been added in parallel with the first one, instead of in series. By what factor would the current delivered by the generator have increased? Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise.
