The units for electric current
WebAmpere or amp (symbol: A) is the unit of electrical current. The Ampere unit is named after Andre-Marie Ampere, from France. One Ampere is defined as the current that flows with electric charge of one Coulomb per second. 1 A = 1 C/s Amperemeter WebElectric Current. Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric …

http://hyperphysics.phy-astr.gsu.edu/hbase/electric/elecur.html Current density is the rate at which charge passes through a chosen unit area. It is defined as a vector whose magnitude is the current per unit cross-sectional area. As discussed in Reference direction, the direction is arbitrary. Conventionally, if the moving charges are positive, then the current density has the same sign as the velocity of the charges. For negative charges, the sign of the current density is opposite to the velocity of the charges. In SI units, current density (symbol: …

WebWhy electric current is not a vector even though it has direction? Explanation: In the case of electric current , although it has direction, but when the two current collides or meets their sum is equal to the algebric sum and not vector sum (i.e it does not follow the parallelogram of vector addition). Hence it is a scalar quantity and is not a vector even though it has … fox news addiction brainwashingWebThe unit of electric current is ampere and the instrument used for the measurement of the current is called Ammeter.
