  3. 3. TODAY’S TOPIC GALVANOMETER INTRODUCTION PRINCIPLE CONSTRUCTION WORKING APPLICATIONS
  4. 4. INTRODUCTION <ul><li>Galvanometer is an electromechanical instrument which is used for the detection of electric currents     through electric circuits. Being a sensitive instrument, Galvanometer can not be used for the     measurement of heavy currents. However we can measure very small currents by using galvanometer but     the primary purpose of galvanometer is the detection of electric current not the measurement of current. </li></ul>
  5. 6. WORKING PRINCIPLE <ul><li>The Basic principle of Galvanometer is PMMC (permanent magnetic moving coil) </li></ul><ul><li>Galvanometer works on the principle of conversion of electrical energy into mechanical energy. When a     current flows in a magnetic field it experiences a magnetic torque. If it is free to rotate under a     controlling torque, it rotates through an angle proportional to the current flowing through it. </li></ul>
  6. 7. WORKING <ul><li>When a current passes through the galvanometer coil, it experiences a magnetic deflecting torque,     which tends to rotate it from its rest position. As the coil rotates it produces a twist in the suspension     strip. The twist in the strip produces an electric restoring torque. The coil rotates until the elastic     restoring torque due to the strip does not equal and cancels the deflecting magnetic torque, then it     attains equilibrium and stops rotating any furthers. </li></ul>
