To solve the problem of finding the value of the capacitance that allows maximum current to flow in an LCR circuit consisting of an inductor, a resistor, a variable capacitor, and an AC source, we can follow these steps: ### Step 1: Understand the condition for maximum current For maximum current to flow in an LCR circuit, the total impedance (Z) must be minimized. This occurs when the inductive reactance (XL) equals the capacitive reactance (XC). Therefore, we can write: \[ X_C = X_L \] ...
