Actions of electric current: thermal, chemical, magnetic, light and mechanical
Electric current in a circuit always manifests itself in some way. This can be either work under a certain load or the accompanying effect of current. Thus, by the action of current it is possible...

Nuclear binding energy. Mass defect
Nucleons in nuclei are in states that differ significantly from their free states. With the exception of the nucleus of ordinary hydrogen, all nuclei have at least two nucleons, between which...
Joule Lenz law formula and definition
Contents: The famous Russian physicist Lenz and the English physicist Joule, conducting experiments to study the thermal effects of electric current, independently derived the Joule-Lenz law. The...
Thermal effect of current: Joule-Lenz law, examples
Moving in any conductor, an electric current transfers some energy to it, which causes the conductor to heat up. Energy transfer occurs at the molecular level: as a result of interaction...
