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

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].
