Questions & Step-by-Step Solutions
In an RLC circuit, what is the condition for resonance?
Step 1: Understand that an RLC circuit has three main components: a resistor (R), an inductor (L), and a capacitor (C).
Step 2: Know that inductive reactance (XL) is the opposition to current flow caused by the inductor, and it depends on the frequency of the current and the inductance value.
Step 3: Understand that capacitive reactance (XC) is the opposition to current flow caused by the capacitor, and it also depends on the frequency of the current and the capacitance value.
Step 4: Recognize that resonance in an RLC circuit happens when the inductor's opposition (XL) is equal to the capacitor's opposition (XC).
Step 5: Write the condition for resonance: XL = XC.
