To measure the supply frequency using series resonant circuit
  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...
