The force on a current carrying conductor places perpendicular to a magnetic field is

The direction of force on a current carrying conductor placed in a magnetic field is given by

Two parallel wires carrying the same current in the same direction placed in 1 cm apart will experience

The deflection produced when unit current passes through galvanometer is called

When number of turns of a moving coil galvanometer is doubled , current sensitivity will be doubled what about voltage sensitivity

To convert a galvanometer as an ammeter we connect which one of the following to the galvanometer

In a circuit, voltmeter should be connected in

The resistance of an ideal ammeter is

A coil of area of cross section 0.5 sq.m with 0 turns is in a plane which is perpendicular to an uniform magnetic field of 0.2 Wb/sq.m. The flux through coil is

The angle between the area vector and plane of the area is

The self inductance of a straight conductor is

Unit of henry can also be written as
