The schematic circuit diagram for studying the characteristics of an a.c. RLC Series Circuit is shown below:

• Voltmeters are connected across the resistance R, inductance L and capacitance C,   to measure the potential drops V_R, V_L, V_C  respectively


• A voltmeter is connected across the power supply for measuring supply voltage V


• An ammeter is connected in series with the elements to measure the current I flowing through each of the elements
