A device that can convert electrical energy into mechanical energy is

When a strong bar magnet is pushed into a coil of insulated copper wire connected to a galvanometer, we will observe a deflection in the galvanometer in

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

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

Ohm’s law express that:

True test of charge is

Copper is not approved to make fuse wire because it:

The electrical resistance of a conductor having cross-sectional area 1 m² and length 1m

Joule’s law of heating implies that heat produced in a resistor is directly proportional to the square of

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

Ankit remarked that he has seen wavering of objects when seen through a stream of hot air rising above a tandoor or a fire. He said that the air just above the fire becomes hotter than the air further higher up. He further said that this wavering can also be seen in the earth’s atmosphere as the earth’s atmosphere is not evenly distributed and several observations can be explained on the basis of this phenomenon,name the phenomeoneon

Why don’t planets twinkle?

Light which consists of only one colour or single wavelength is called Monochromatic

When a person can see faraway objects but not nearby objects.
