Electric current
An electric current is the flow of electric charge within a conductor, such as a wire. It is caused by the movement of electrons, which are negatively charged particles, in a particular direction.
About
It is caused by the movement of electrons, which are negatively charged particles, in a particular direction. The strength of the current is measured in amperes (A), and its direction is defined as the direction in which positive charges would flow. Electric currents are essential in various applications, including powering electrical devices, transmitting signals, and generating magnetic fields. The flow of electric current is governed by Ohm's law, which relates the current to the voltage and resistance in a circuit. Understanding electric currents is crucial in fields such as electrical engineering and physics.
