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 VR, VL , VC  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.
