What are independent and dependent sources?
whose output value doesn’t depend upon the circuit parameters like voltage and current.
What is Thevenin equivalent circuit?
Thevenin Equivalent Circuit states that any two terminal linear network having a number of voltage current sources and resistances can be replaced by a simple equivalent circuit consisting of a single voltage source in series with a resistance, where the value of the voltage source is equal to…
What is a Thevenin’s theorem?
Thevenin’s Theorem. Thevenin’s theorem is a procedure by which we change a complex network in to simple network called thevenin’s equivalent circuit. Thevenin’s equivalent circuit of an open circuit voltage, thevenin voltage, V th and the total resistance from the open terminals side, thevenin’s equivalent resistance, R th.
An independent voltage source maintains a voltage (fixed or varying with time) which is not affected by any other quantity. They are called dependent voltage (current) sources or controlled voltage (current) sources , and their usual symbols are shown in figure 1.4.
What is DC circuit theory?
DC Circuit Theory The fundamental relationship between voltage, current and resistance in an electrical or electronic circuit is called Ohm’s Law. All materials are made up from atoms, and all atoms consist of protons, neutrons and electrons. Protons, have a positive electrical charge.
What is a dependent source?
In the theory of electrical networks, a dependent source is a voltage source or a current source whose value depends on a voltage or current elsewhere in the network. Dependent sources are useful, for example, in modelling the behavior of amplifiers. A bipolar junction transistor can be modelled as a dependent current…
