AC Fundamentals

AC Fundamentals: Let us discuss in brief, the AC Fundamentals necessary to analyse the networks consisting of various alternating current and voltage sources, resistances and inductive, capacitive reactances. An alternating current or voltage is the one which changes periodically both in Cycle magnitude and direction. Such Change in magnitude and direction is measured in terms […]

Power and Energy

Power and Energy: Power and Energy – Power is the rate of change of energy, and is denoted by either P or p. If certain amount of energy is used over a certain length of time, then where dw is the change in energy and dt is the change in time. We can also write […]
