Electrolysis, examples and importance

Electric current can be conducted through a liquid or liquids by the process of electrolysis. What is electrolysis?  Electrolysis can be defined as decomposition of a certain liquid and solution into their component parts when electricity is passed through them.  Electrolysis cannot be discussed without talking about electrolyte, ions,   voltameter  and  electrodes. What is electrolyte?  It can be …

Transformers, Equation of transformer in physics

Definition of Transformers Transformers are devices use for changing the voltages or currents of an A.C supply. The transformers may be used to increase or decrease the A.C (alternating current) supply. The transformers make use of the properties of mutual inductance to change the voltage of the alternating current (A.C) supply. Transformer may be used …
