The electrons still rotate around the nucleus due to the attraction force between the protons in the nucleus and electrons. The electrons may leave the atom and move freely due to the weakness of...
Secondary Cells are characterized by reversible chemical reactions, These cells can be recharged by passing an electric current from external source between their poles in a direction opposite to the discharge process, Secondary Cells...
Hydrogen electrode is used as a standard electrode in measuring the electric potential of other electrodes because its potential equals zero, the standard hydrogen potential is not equal zero in some cases because it...
Electrochemistry is a branch which is interested to study the exchange conversion of chemical energy and electrical energy through oxidation & reduction, Electrochemistry means chemistry of electrons because the electrons transfer from one point...
AC dynamo generates an alternating current which its intensity increases from zero to maximum value then drops to zero again in the first half cycle, next to that, the current direction is reversed and...
Alternating current generator is a device which converts the mechanical energy into electric energy, When the coil rotates between the two poles of the magnet, it intercepts the magnetic flux lines which generates the...
