The law of conservation of energy states that energy cannot be created no destroyed, but it can be converted from one form to other. Electrical technology isn't also against it. Here are some examples of energy conservation which belongs to electrical technology.

  • Electromechanical energy conservation, Faraday's invention produced electrical energy from mechanical energy of rotation. Mechanical energy is derived from the thermal energy by a turbine. In turn, the thermal energy is obtained from chemical energy by burning fossil fuel or nuclear fuel. Sometimes the conversion is from hydraulic energy by hydro-electric generation.
  • Electrochemical energy conversion as in batteries.
  • Magnetohydrodynamics(MHD) energy conversion.
  • Photovoltaic energy conversion as in the solar cell.

Definitions of Electrical Circuits

An electric circuit is a path of connected elements in which electrons can flow from a voltage or current source. Before going into discussion of network analysis or Circuit is required to know certain definitions.

Standard Input Signals

A signal is function of independent variable that carry some information. Practically the input and also output signals of any system are complex (they are combination of other signal) in nature. Thus it is being tough to analyze the characteristic performance of any system by those signal.
