An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma). Electric current A simple electric circuit, where current is represented by the letter i. The relationship between the voltage (V), resistance (R), and current (I) is V=IR; this is known as Ohm's law. The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter.[3] Electric currents cause Joule heating, which creates light in incandescent light bulbs. They also create magnetic fields, which are used in motors, inductors and generators. The moving charged particles in an electric current are called charge carriers. In metals, one or more electrons from each atom are loosely bound to the atom, and can move freely about within the metal. These conduction electrons are the charge carriers in metal conductors. class 12 physics chapter 3 in hindi. physics chapter 3 class 12 for board exam revision by blue sky. class 12 physics chapter 3 combination phy class 12 chapter 3. current electricity 12 board, cbse physics 12 board, physics class 12 chapter 3 in hindi, physics class 12 chapter 3 NCERT solutions, physics class 12 chapter 3 NCERT, physics class 12 chapter 3 current Electricity, physics class 12 chapter 3 numerical, physics class 12 chapter 3, physicsclass 12 chapter 3 in hindi nçert These are the revision notes .
