Electrical Energy, has several effects such as :
-Electro mechanical effect
Two current carrying conductors have mechanical attraction or repulsion due to magnetic fields. -Electrical energy can be converted into mechanical energy and vice-versa (motor, generator) -Electro-Thermal Effect
Current passing through a conductor produces heat due to I2Rt losses. This is also called Joule effect. (electrical ovens furnaces) I2Rt losses are converted to heat.
-Electro Chemical Effect
current passing through electrolyte produces electrolysis (electroplating)
-Biological effect
-Electrical energy has effect on biological cells, Electric current through a human body or a bio-plant produces biological reactions, (e.g. electric shocks, electro-therapy)
