To measure the supply frequency using series resonant circuit

Image
Aim of the experiment : To measure the supply frequency using series resonant circuit.  Apparatus Required :  SL.No. Name of the apparatus  Range Make Make No.  Quantity 1. Supply source 0-30v, AC 1 2. Ammetre 0-100mA 1 3. Voltmeter 0-50v 1 4. Resistance 25 ohm 1 5  Inductance  1-10 H 1 6. Capacitance  3 micro Farad 1 Theory :          We know that-          Impedance, Z= √{R 2 +(X L - X C ) 2 }          Where X L =WL & X C =1/WC          when X L =X C then Z=R           =>WL=1/WC           =>W 2 =1/LC           =>W=1...
