The capacity of a storage reservoir is determined on the basis of the inflow to the reservoir and the demand of the consumers (or the yield of the reservoir). The following two methods are generally used for determining the capacity of a storage reservoir: 1. Analytical Method: In this method an analysis of demand and inflow of water per month [...]

In this article we will discuss about the independent, dependent and ideal sources of energy. Independent and Dependent (or Controlled) Sources of Energy: The source (voltage or current) may be independent or dependent. A source is said to be independent when it does not depend on any other quantity in the circuit. Fig. 1.15 (a) shows an independent dc voltage [...]
