Tangent galvanometer measures

Options

  1. Acapacitance
  2. Bcurrent
  3. Cresistance
  4. Dpotential difference

Correct answer

B. current

Step-by-step solution

When a current is passed through the galvanometer coil, then a magnetic field B is produced at right angles to the plane of the coil, ie, at right angles to the horizontal component of earth's magnetic field H . Under the influence of two crossed magnetic fields B and H , the magnetic needle of galvanometerundergoes a deflection which is given by the tangent law. Using tangent law, we can find a relation I Which clearly indicates that tangent galvanometer is an instrument used for detection of electric current in a
