SERIES RESONANCE

Introduction | Questions | Quiz
 INTRODUCTION Resonance occurs in a series R-L-C circuit when inductive and capacitive reactances are equal. Resistance does not affect the resonant frequency. Formula for calculating resonant frequency: f = 1 000 000 / 2pi * squarer root of (LC ) f = frequency in kilohertz L = inductance in microhenrys C = capacitance in picofarads 2pi = 6.28 Note: Use calculator to compute values. Look closely at the values of L and C. If the values are small, the resonant frequency is high and all answers in kHz can be eliminated. A-001-003-001....
