<p>The current, in the LCR circuit shown in the figure is observed to lead the voltage in phase. Without making any other change in the circuit, a capacitor, of capacitance <span class="equation">\(C_{0}\)</span>, is (appropriately) joined to the capacitorC. This results in making the current, in the &#39;modified&#39; circuit, flow in phase with the applied voltage.</p>
