The resonant frequency for a RLC circuit is calculated from Equation 15.6.5, which comes from a balance between the reactances of the capacitor and the inductor. Since the circuit is at resonance, the impedance is equal to the resistor. Then, the peak current is calculated by the voltage divided by the resistance.

WebReactance is symbolized by the capital letter “X” and is measured in ohms just like resistance (R). Capacitive reactance can be calculated using this formula: XC = 1/ (2πfC) Capacitive reactance decreases with increasing frequency. In other words, the higher the frequency, the less it opposes (the more it “conducts”) AC current. WebThe peak value is the greatest value of either voltage or current that the waveform reaches during each half cycle measured from the zero baseline. Unlike a DC voltage or current which has a steady state that can be measured or calculated using Ohm’s Law , an alternating quantity is constantly changing its value over time.
