The Coulomb force on a charge of magnitude at any point in space is equal to the product of the charge and the electric field at that point =. The SI unit of the electric field is the newton per coulomb (N/C), or volt per meter (V/m); in terms of the SI base units it is kg⋅m⋅s −3 ⋅A −1 .
newton per coulomb (N⋅C −1), or equivalently, volt per meter (V⋅m −1) energy: joule (J) Young's modulus: pascal (Pa) or newton per square meter (N/m 2) eccentricity: unitless Euler's number (2.71828, base of the natural logarithm) unitless electron: unitless elementary charge: coulomb (C) force
The newton (N) is equal to one kilogram-metre per second squared (1 kg⋅m⋅s −2). The pascal (Pa) is equal to one newton per square metre (1 N⋅m −2). The joule (J) is equal to one newton-metre (1 N⋅m). The watt (W) is equal to one joule per second (1 J⋅s −1). The coulomb (C) is equal to one ampere second (1 A⋅s).
The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). [ 1 ] [ 2 ] It is defined to be equal to the electric charge delivered by a 1 ampere current in 1 second .

The SI unit of quantity of electric charge is the coulomb (symbol: C). The coulomb is defined as the quantity of charge that passes through the cross section of an electrical conductor carrying one ampere for one second. [6] This unit was proposed in 1946 and ratified in 1948. [6] The lowercase symbol q is often used to denote a quantity of ...
What is plain from this definition, though, is that the unit of E is N/C (newtons per coulomb). This unit is equal to V/m (volts per meter); see below. In electrostatics, where charges are not moving, around a distribution of point charges, the forces determined from Coulomb's law may be summed. The result after dividing by q 0 is:
Rural electrification systems tend to use higher distribution voltages because of the longer distances covered by distribution lines (see Rural Electrification Administration). 7.2, 12.47, 25, and 34.5 kV distribution is common in the United States; 11 kV and 33 kV are common in the UK, Australia and New Zealand; 11 kV and 22 kV are common in ...
