Consider an RLC series circuit with a 16 ohm resistor, 0.08 henry inductor, and 0.04 farad capacitor connected to a 120 volt source with a 50 hertz frequency. Determine the circuit's impedance, phase angle, current amplitude, and voltage amplitude across each circuit element. To solve the problem, identify the known and unknown quantities. By recalling the reactance equations and substituting the terms, the inductive and capacitive reactance in the circuit can be determined. Using the impedance equation and substituting the resistance and reactance values, the impedance of the circuit can be determined. Recalling and substituting the terms in the phase angle equation, the phase angle between the current and voltage can be determined. In an RLC series circuit, impedance is a ratio of voltage and current amplitude; by rearranging the equation, the current amplitude can be determined. The voltage amplitude across each element can be determined as the product of the element's current and resistance or reactance. By substituting the value in the equations, the voltage amplitude across each element can be determined.
