# Frequent question: What is meant by electric field intensity write its SI unit?

Contents

## What is electric field write its SI unit?

Electric fields are important in many areas of physics, and are exploited practically in electrical technology. … The derived SI units for the electric field are volts per meter (V/m), exactly equivalent to newtons per coulomb (N/C).

## What is intensity and its SI unit?

Intensity is an objective measure of the time-averaged power density of a wave at a particular location. The SI unit of intensity is the watt per square meter .

## What is meant by intensity of electric field write its SI quantitative and dimensional formula?

The dimensional formula for electric field intensity is: A.) [MLT−3A−1] … \$E=dfrac{F}{q}\$ , where E is electric field intensity, F is the force exerted on charge and q is charge. So, to obtain a dimension of electric field intensity we will divide the dimension of force and charge.

## What is SI unit of mobility?

The SI unit of velocity is m/s, and the SI unit of electric field is V/m. Therefore the SI unit of mobility is (m/s)/(V/m) = m2/(V⋅s).

## What is electric field formula?

Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. The formula of electric field is given as; E = F /Q.

GOOD TO KNOW:  What is a major factor that limits the efficiency of photovoltaic devices?

## What is the SI unit of intensity of sound?

Sound intensity is the sound power per unit area, the SI unit is watt per square metre (W/m2). Sound pressure is the difference between the pressure caused. by a sound wave and the ambient pressure of the medium it is passing through.

## What is intensity equal to?

Intensity is defined to be the power per unit area carried by a wave. … In equation form, intensity I is I=PA I = P A , where P is the power through an area A. The SI unit for I is W/m2.

## What is S.I unit of electric dipole moment?

The SI composite unit of electric dipole moment is the ampere second meter.

## What is dimensional formula?

Hint – Dimension formula is the expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T. … These will specify the nature of the unit and not its magnitude.

## What is the dimension of intensity of electric field?

Or, E = [M1 L1 T2] × [I1 T1]1 = [M1 L1 T3 I1]. Therefore, the Electric Field is dimensionally represented as [M1 L1 I1 T3].
