Newtons per Coulomb ( N/C) has a dimension of MLT–3I–1 where M is mass, L is length, T is time, and I is electric current. It is essentially the same as the equivalent standard SI unit V/m.
Yes. Newtons per coulomb is force per unit charge – this is the electric field strength, which is also the derivative of electric potential: volts per meter.
Therefore we see that both units, Newtons per Coulomb NC−1 and Volts per meter Vm−1, are the same and both are used interchangeably to define the electric quantity field.
The coulomb (symbolized C) is the standard unit for electric charge in the International System of Units (SI). It is a dimensionless quantity that shares this aspect with the mole. A quantity of 1 C is approximately equal to 6.24 x 1018 or 6.24 trillion.
Joule is a unit of work done and coulomb is a unit of charge. Potential is defined as the ratio of work done to charge and the unit of potential difference is volts. Therefore, one joule per coulomb is equal to the unit potential difference. Therefore, it is equivalent to one volt.
A newton per coulomb (N/C) is the derivative SI unit of electric field strength. The force of 1 NC is achieved when a voltage of 1V is applied between two infinite parallel planes 1m apart.
It can also be expressed as ampere times ohm, joule per coulomb (energy per unit charge) or watt per ampere (power per unit current). And finally, volt can be given in SI base units as 1 V = 1 kg m2 s–3 A – 1 (one square kilometer per cubic meter per ampere).
A coulomb is an enormous charge – two 1C charges 1 m apart exert a force of 9 x 109 Newtons (see Coulomb’s law). p>
