Questions & Step-by-Step Solutions

What is the resonant frequency of a series RLC circuit? (2020)
  • Step 1: Understand that a series RLC circuit consists of a resistor (R), an inductor (L), and a capacitor (C) connected in a single loop.
  • Step 2: Know that the resonant frequency is the frequency at which the circuit can oscillate with maximum amplitude.
  • Step 3: Learn the formula for resonant frequency, which is f = 1/(2π√(LC)).
  • Step 4: Identify the values of L (inductance in henries) and C (capacitance in farads) in your circuit.
  • Step 5: Plug the values of L and C into the formula to calculate the resonant frequency (f).
  • Step 6: Perform the calculations to find the value of f, which will be in hertz (Hz).
