# what is the cgs unit of electric charge?

1 answer. 1 Coulomb = 3 × 10 9 esu ... One of them is given negative charge and the other is charged positively. In the first, charge is in Franklins, and current is in statampere. The SI unit of current is ampere which measures the flow of electric charge across a surface at the rate of one coulomb per second.Since the charge is measured in coulombs and time in seconds, so the unit is coulomb/Sec (C/s) or amp.Meanwhile, the formula for electric current is given as follows: 1 e.s.u= 1/3 * 10^-9 C So how do we derive the CGS unit of electric current The cgs unit for electric charge is the “electrostatic unit”, or esu. On the other hand, in measurements of electromagnetic phenomena (involving units of charge, electric and magnetic fields, voltage, and Therefore, two charges each with charge 1 esu sitting 1 cm apart will feel a force between them of 1 dyne. Area = product of two lenghts e.g. For example, the CGS unit of force is the dyne, which is defined as 1 g⋅cm/s 2, so the SI unit of force, the newton (1 kg⋅m/s 2), is equal to 100,000 dynes. See the reference. The size of the esu is set so that the constant in Coulomb’s force law is equal to one. It is called the electrostatic unit (esu), or sometimes the statcoulomb, and is simply2 esu p dyne cm 2= g1=2 cm3= =s (12) 2Recall that the unit of force in CGS is called the dyne g cm=s2 = 10 5 N. 3 The SI unit of current is Ampere 1 Ampere = 1 Coulomb/1 Second and i know dat CGS unit of charge is e.s.u. The magnitude of the charge of an electron is e=4.8×10-10 esu. Contributor; Definition. There is no such thing as the cgs unit for any electromagnetic quantity. The CGS unit of charge is esu or stat-coulomb and SI unit of charge is Coulomb (C). One CGS esu of charge (also known as the statcoulomb) is that charge which, if placed 1 cm from a similar charge in vacuo, will repel it with a force of 1 dyne.. There are actually two different ways within the CGS system to define those units, electrostatic and electromagnetic. CGS (11) The unit of charge in CGS is derived in terms of centimeters, grams, and seconds. area of a square = (side lenght of the square)^2 =product of two side lenghts of the square (As all of the 4 side lenghts of a square are same). In the second, charge is in abcoulombs, current is in abamperes. asked Mar 28 in Electric Field by Sandhya01 (59.1k points) electric field; class-12; 0 votes. The following exercises will be instructive. The CGS unit of lenght is cm (or centimeter). What is the SI Unit of Electric Current? In SI system, 1/4πε0 = 9 × 10^9 N.m^2/C^2 1 N = 10^5 dyne 1m = 100cm Unit of charge in CGS unit is know as statcoulomb. where ε 0 is the electric constant.The effect of the Gaussian-cgs definition is to fold the "1/4πε 0" factor into the definition of the statcoulomb by setting it equal to unity in terms of length, mass, and time; which results in the Gaussian unit of electric charge possessing the cgs dimensions of L 3/2 M 1/2 T −1. In electrostatic units, electrical charge is defined by the force that it exerts on other charges. The electrostatic system of units (CGS-ESU) is a system of units used to measure quantities of electric charge, electric current, and voltage within the centimeter–gram–second (or "CGS") system of metric units.
