Production of AC Voltage The machines which are used to generate electrical voltages are called generators. The generators which generate purely sinusoidal a.c. voltages are called alternators. The basic principle of an alternator is the principle of electromagnetic induction. The sine wave is generated according to Faraday’s law of electromagnetic induction. It says that whenever there is … Read more
Norton’s Theoram Notes Where as Thevenin’s theorem was used to simplify a network to a constantvoltage source and a series resistance. Norton’s theorem can be used to resolve a network into a constant-current source and a parallel resistance. The interchange of voltage sources and current sources by use of Thevenin’s and Norton’s theorems is sometimes useful in … Read more
Thevinen Theorem Notes Statement : Any combination of linear bilateral circuit elements and active sources, regardless of the connection or complexity, connected to a given load RL, may be replaced a simple two terminal network consisting of a single voltage source of volts and a sing resistance RTH in series with the voltage source, across the two terminals of … Read more
