Although people have been killed by as little as 120-volt AC and low voltage DC, the silent killer is the amount of amperage in milliampers that flow through a person's body. Any electrical device is capable of dealing a deadly blow, depending on the amount of current flowing. Electric Current Definition. An electric current is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge.If the electric charge flows through a conductor, we say that there is an electric current in the conductor.In the circuits using metallic wires, electrons constitute a flow of charges As electric current is conducted through a material, any opposition to that flow of electrons (resistance) results in a dissipation of energy, usually in the form of heat. This is the most basic and easy-to-understand effect of electricity on living tissue: current makes it heat up

When an electronic current flows through a wire, it generates a magnetic field. Magnetic fields are an important concept in electricity.

Since the Voltages are the same no current can flow through the wires. When you attach a load to the secondary, the voltage generates a current which causes it to collapse some of the electric field. The back emf on the primary collapses in sympathy. That unbalances the voltages in the primary and current flows from the generator. A FINAL. For example, if a wire becomes exposed and touches the metal frame of a device, current can flow along the outside causing the potential for injury and death if someone touches the charged device. A short circuit, as suggested by the name, provides electricity with a shorter path to ground or to equalize electrical potential across two terminals For any electrolysis the electrical charge Q passing through an electrode is related to the amount of electrons n e - by \[F=\dfrac{Q}{n_{e^-}}\] Thus F serves as a conversion factor between \(n_{e^-}\) and \(Q\). Often the electrical current rather than the quantity of electrical charge is measured in an electrolysis experiment We can get an idea of how fast the drift velocity is by taking some typical values of current and wire dimensions. Let's think of a current of 5 A that is flowing in a copper wire with a cross section of 0.5 mm 2 (= 0.5 * 10-6 m 2) For copper, n = 8.5 × 10 28 per m 3 The charge on an electron, Q = 1.6 × 10-19 C. So, I = n A v Q A current can be induced in a conducting loop if it is exposed to a changing magnetic field. This change may be produced in several ways; you can change the strength of the magnetic field, move the conductor in and out of the field, alter the distance between a magnet and the conductor, or change the area of a loop located in a stable magnetic field Electromagnetic induction was discovered by Michael Faraday, published in 1831. It was discovered independently by Joseph Henry in 1832.. In Faraday's first experimental demonstration (August 29, 1831), he wrapped two wires around opposite sides of an iron ring or torus (an arrangement similar to a modern toroidal transformer).[citation needed] Based on his understanding of electromagnets.
