Fleming’s Right-hand rule gives:

Magnetic effect of current was identified by:

Relative strength of magnetic field at a point in the space adjoining the magnet is shown by the:

Direction of rotation of a coil in electric motor is intent by:

A D.C generator works on the theory of:

To determine the direction of force experienced by a current carrying conductor placed in a uniform magnetic feld.

The phenomenon discovered by Faraday.

You are holding the current-carrying wire in your right hand so that your thumb points in the direction of current, then the direction in which your fingers encircle the wire will give the direction of the magnetic feld lines around the wire.explain

Electrical resistivity of a given metallic wire depends upon:

A boy records that 4000 joule of work is required to transfer 10 coulomb of charge between two points of a resistor of 50 Ω. The current passing through it is:

To get 2 Ω resistance using only 6 Ω resistors, the number of them required is

True test of charge is

The commercial unit of electric energy is

S.I unit of resistivity

At the time of short circuit, the electric current in the circuit

When a 4 V battery is connected across an unknown resistor there is a current of 100 mA in the circuit. The value of the resistance of the resister is

A clear sky appears blue, because:

The absorption of light by a molecule depends on the

What would have been the colour of sky if the earth had no atmosphere

Milk is a colloid that contains globules of fat and protein. When a beam of light is directed at a glass of milk the light is scattered. That is a great example
