Question

Volt-meter is the SI unit of ………?

Answer 1

Hint:Potential difference is defined as the change in the potential energy of a unit charge from point A to point B which is connected by a circuit. The SI unit of potential difference is Volt and the SI unit of distance is meter.

Complete answer
It is asked in the problem that which physical quantity has SI unit of Volt-meter.

The SI unit of the potential difference is Volt and the SI unit of the distance is meter. We need a physical quantity that has its SI unit as Volt-meter.

Flux is the physical quantity which has SI unit Voltmeter. There are different types of fluxes like magnetic flux, electrical flux and many more.

Additional information:The electrical flux is defined as the electric field per unit area of flow; also the magnetic flux is the magnetic field per area of section. Flux can be calculated of the quantities which are flowing.

If a charge is put inside a spherical conductor then the flux coming out of the spherical conductor is equal to ratio of enclosed charge to the permittivity of free space. The magnetic flux is the product of the magnetic field and area of the cross section of the conductor or coil.

Note:It is advisable for students to understand and member the concept of flux and also remember the SI units of various physical quantities. The flux is defined as the flow per unit area. The flux can be calculated anywhere the phenomenon of flow takes place. The formula of flux is different for different quantities but the sense is always the same.
