Which unit or units can be used for the unit of electric field strength?

The value of the electric field has dimensions of force per unit charge. In the metre-kilogram-second and SI systems, the appropriate units are newtons per coulomb, equivalent to volts per metre.

What is the symbol and unit of electric field strength?

SI electromagnetism units

SI electromagnetism units v t e
Symbol Name of quantity Unit name
E electric field strength volt per metre
D electric displacement field coulomb per square metre
ε permittivity farad per metre

Which is not unit of electric field?

From the above equation, the unit of force is newton ($N$) and the unit of charge is coulomb ($C$). Therefore, the unit of electric field will be $dfrac{N}{C}=N{{C}^{ -1}}$. Therefore, the unit which is not a unit of electric field is $J,{{C}^{ -1}}$. Hence, the correct option is (B).

What is a strong electric field?

A strong electric field applied between the sharp-edged exit of the capillary and an external electrode causes charge separation inside the liquid propellant, which is doped with an additive to increase its electric conductivity.

What is K in electric field?

The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. In SI units it is equal to 8.9875517923(14)×109 kg⋅m3⋅s2⋅C2.

What is the SI unit of e h?

The impedance Z is merely the ratio E/H of the electric to the magnetic field. The SI units of E and H are V/m and A/m respectively, so the SI units of Z are V/A, or ohms, Ω.

What is SI unit of magnetic field?

The tesla (symbol T) is the derived SI unit of magnetic flux density, which represents the strength of a magnetic field. One tesla represents one weber per square meter.
