Measure of electrical current
WebDefinition: Electric current is defined as the rate of flow of negative charges of the conductor. In other words, the continuous flow of electrons in an electric circuit is called an electric current.The conducting material consists a large number of free electrons which move from one atom to the other at random. Unit of Current Current can be measured using an ammeter. Electric current can be directly measured with a galvanometer, but this method involves breaking the electrical circuit, which is sometimes inconvenient. Current can also be measured without breaking the circuit by detecting the magnetic field associated … See more An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. … See more The conventional direction of current, also known as conventional current, is arbitrarily defined as the direction in which positive charges flow. In a conductive material, the moving charged particles that constitute the electric current are called See more In alternating current (AC) systems, the movement of electric charge periodically reverses direction. AC is the form of electric power most commonly delivered to businesses and … See more Joule heating, also known as ohmic heating and resistive heating, is the process of power dissipation by which the passage of an … See more The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity). Current intensity is … See more Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points.
