WebDec 21, 2024 · The formula for the Q-factor of the RLC circuit is: Q = 1/R × √ (L/C) where the new symbols are: Q – Q-factor; and R – Resistance. For the circuit that we considered before with L = 1 µH and C = 2 pF, the resistance R = 1 kΩ leads to the Q-factor Q = 0.7 (try these values in the RLC circuit calculator). This value of the Q-factor is rather small.
