Air conditioning is the process of improving air quality in a building or a vehicle by altering the humidity and temperature in the air into more favorable conditions. It involves all forms of technological cooling, heating, ventilation, or disinfection that modifies and enhances air quality.

An electrical resistor is a passive electrical component that prevents an excess inrush of current into a circuit. As electricity plays a significant role in modern life, electrical resistors have a broad range of applications and markets. Power generation, transmission, and distribution sectors account for extensive use of resistors. With the demand for electricity showing an exponential increase globally, governments in various countries are undertaking development and modernization of their power generation infrastructure. Population growth and increased urbanization have fueled residential, commercial, and industrial construction activities, thereby resulting in the need to expand electricity T&D networks worldwide.

Earthing is a grounding process for electricity carrying devices. During earthing, the neutral wire or the wire that does not carry electricity in an apparatus is connected to the ground. The purpose of earthing an electrical device is to minimize and prevent the danger of electrocution and fire break-outs that can be caused by an electrical energy discharge. This is achieved by ensuring that there is no leakage in the flow of current through an undesired path and through proper insulation so that the potential of the conductor is below that of the earth.
