A high-pass filter consists of a 210. Ω resistor and a 5.80 μF capacitor in series with each other. If the AC source has a peak voltage of 2.80 V and the cross over frequency is equal to the frequency, what is VR?
For a 4.60 μF capacitor and a 7.40 μH inductor to have the same reactance, what frequency must they have?
A toaster oven dissipates 1.47×103 W of power when connected to a power line that has a voltage rating of 115 V and a frequency of 77.0 Hz. What is the resistance of the toaster oven?
