Q: What is the phase difference between the voltage and current in a series RLC circuit at resonance? (2023)

Solution: At resonance in a series RLC circuit, the phase difference between voltage and current is 0°.

Steps: 6

Step 1: Understand what a series RLC circuit is. It consists of a resistor (R), inductor (L), and capacitor (C) connected in a single loop.
Step 2: Learn about resonance in a circuit. Resonance occurs when the inductive reactance (XL) and capacitive reactance (XC) are equal.
Step 3: At resonance, the effects of the inductor and capacitor cancel each other out.
Step 4: When the inductor and capacitor cancel each other, the circuit behaves like a pure resistor.
Step 5: In a pure resistive circuit, the voltage and current are in phase, meaning they reach their maximum and minimum values at the same time.
Step 6: Therefore, the phase difference between voltage and current at resonance is 0°.
