Synopsis of Electrical Engineering

Electrical energy has following effects: 1. Biological effect: Electrical energy has effect on biological cells. Electrical current through human body or living beings produces biological reactions. Example: electrical shock. 2. Electro-mechanical effect: Two current carrying conductors have mechanical attraction or repulsion due to the magnetic field produced by them. It may be noted that, electrical energy can be converted to mechanical energy by using motors and mechanical energy can be converted to electrical energy by using generators. 3. Electro-thermal effect: Electrical current passing through a conductor produces heat due to losses. This effect will be normally used in Electric Ovens and Furnaces. 4. Electro chemical effect: Electric current passing through electrolyte produces electrolysis. Example: electroplating.
