**Mechanical Electrical Analogy**

The concept of an analogous system is very useful in practice. Since one type of system may be easier to handle experimentally than other. A given electrical system consisting of resistance, inductance and capacitance may be analogous to the mechanical system consisting of a suitable combination of dashpot, mass, and spring.
