Question # 1

State Ohm's law and basic principle of electroplating.

  • Ans 1: Current passing through a wire is directly proportional to the potential difference applied across its ends provided that the physical state conductors remains same.
    Basic principle of electroplating is a process of coating a thin layer of sum expensive metal of (gold,silver etc) on a article of some cheap metal.

Question # 1

A voltmeter can not read the exact EMF of the cell.Why?

  • Ans 1: When a voltmeter is connected across a cell,it will draw some current from the cell and small potential drop takes place due current flowing through the internal resistance of the cell.As a result the actual emf of the cell decrease and the voltmeter cannot read exact value.

Question # 1

Briefly describe the current through a metallic conductor and drift velocity.

  • Ans 1: In a metallic conductor,free electron are in random motion with the speed of several hundred km/s at the room temperature.If the ends of the wire are connected to the battery the free electrons are experience a force and directed to move in the electric field direction.The accelerating electrons keep on colliding with atoms of the conductors and transfer their energy to the lattice with the result that the electrons acquire an average velocity called drift velocity.The drift velocity is of the order of 10-3.A steady current is establish in the wire.
