What is the use of the meter bridge experiment?

Use of meter bridge experiment:

The meter bridge experiment is used to test the laws of resistance and figure out unknown resistances.

  • Meter Bridge wire is made of copper-nickel alloy (constantan), alloy manganin, and chromium, nickel, and iron alloys (nichrome) as they are resistant to corrosion.
  • They have cold temperatures and a high melting point of around 1400 degrees Celsius.
  • A meter bridge is an electrical device that is used to calculate the resistance of a conductor.

It can also be used to determine the series and parallel equivalent of resistances.

            A charged particle $+q$ in an electric field $\vec{E}$ experiences a force in the direction of the electric field. As a result, its kinetic energy changes. Similarly, the charged particle also experiences a force when it moves in a magnetic field $\vec{B}$. But this magnetic force is perpendicular to both velocity $\vec{v}$ of the charged particle and the magnetic field $\vec{B}$, so it cannot change the kinetic energy of the charged particle. Consider two charged particles 1 and 2 of masses $m$ and $\frac{m}{2}$ having charges $-q$ and $+2q$ respectively. They are accelerated from rest through the same potential difference $V$ and acquire kinetic energy $K_1$ and $K_2$. Then they enter in a region of uniform magnetic field $\vec{B}$ perpendicular to their velocities.

                A p-type or n-type semiconductor can be converted into a p-n junction by doping it with suitable impurity. The motion of majority charge carriers causes diffusion current across the junction while the barrier electric field causes motion of minority carriers for drift current. In case of unbiased diode, the diffusion and drift currents are equal. This equilibrium is disturbed by the biasing batteries. Diodes, therefore, allow currents in one direction. This property of diode is used in making rectifiers.
