In an AC circuit with a single capacitor, how is the current to and from the capacitor related to the voltage across the capacitor? The current leads the voltage by 90*- The current and voltage are in phase. The voltage leads the current by 90. The relationship depends on the frequency of the source.Question 1 An RC filter has a cross over frequency of 613 Hz. If the resistance of the filter is 59.0 0, what is the capacitance of the filter? O 0.000260 F 4.40*10" F O 4.47x106 F O 4.33x10" F Question 2 For a 1.80 pF capacitor and a 5.30 JH inductor to have the same reactance, what frequency must they have? O 0.273 Hz O 5.15x10# Hz O 7.98x10# Hz O 0.492 Hz Question 3 A battery, with an rms voltage of 23.0 V, is connected to a resistor. The resistor dissipates 5.10 W of power at this rms voltage. What rms voltage would the battery need to have so that the resistor dissipated 18.0 W of power? O 43.2 V O 12.2 V O 23.0 V O 2.80x103 V
