What does Thevenin's equivalent circuit consists?
The Thevenin's equivalent circuit consist of a voltage source in series with a resistor.
Why an independent voltage source is deactivated by short circuiting it?
A voltage source (V) is modeled by connecting its internal impedance (Zg) in series. If we determine the impedance across the voltage source terminals, it should be Zg, and it is possible only if the voltage source is short-circuited.An equivalent current source is modeled by connecting the current source (V/Zg) in parallel with the internal impedance Zg. For the two sources to be equivalent, their impedances across their terminals must be equal. This is possible only if the current source is open-circuited.
How can convert voltage source into current source?
Take the internal series resistance of the voltage source and make it the internal parallel resistance of the current source. Then compute using Ohm's law the current of the current source to be equal to the maximum current the original voltage source could supply a short circuit load. Note: the two sources are equivalent.
Why do you replace voltage sources with short circuits and current sources with open circuits in thevenin's theorem?
The equivalent of an inactive Thevenin voltage source is a source with zero voltage between its terminals regardless of the current through it, best represented by a zero resistance, i.e. a short-circuit. The equivalent of an inactive Norton current source is a source through which no current can flow regardless of the voltage across it, best represented by an infinite resistance, i.e. an open circuit.
What is source of voltage?
Energy is the source of voltage
How do you calculate thevenis resistance in thevenis ckt?
First,remove all current and voltage sources ie replace voltage source with a short and keep current source open.Now draw the equivalent resistance-only circuit and find the equivalent resistance as viewed from the terminals of the circuit.
When the RL changes how does this affect the Nortons or Thevenins equivalent circuit?
When the load resistance (RL) changes, it affects the Norton or Thevenin equivalent circuit by altering the output voltage and current delivered to that load. For a Thevenin equivalent, the output voltage can change based on the voltage divider effect, while for a Norton equivalent, the output current will vary according to the current division principle. This means that the values of the equivalent voltage source (Vth) or current source (In) remain constant, but the load will experience different voltage and current levels depending on its resistance. Consequently, the overall power delivered to the load will also change.
Why thevenin's and norton's theorem are equivalent?
thevenin's and norton's theorems are equivalent.theoritically both can be derived from each other.if we consifder thevenin's equivalent circuit it consists of voltage source in series with thevenin's resistance .but an equivalent circuit can be obtained by replacing thevenin's voltage source by an equivalent current source with a resistance ioe thevenin's resistance in parallel which gives us norton's circuit.mathematicaaly both are interconvertible using ohm's law
Is it possible to use source transformation to dependent voltage source?
Yes.Source transformation in dependent voltage source can be solved the same like independent voltage source
What are voltage controlled voltage source?
when the magnitude of voltage of a source is controlled by another small voltage source in the circuit the former is called voltage controlled voltage source and the later is called controller voltage source.
What is the voltage source and what is the conductor in a circuit?
The voltage source is the source of the electricity. The conductor is what the electricity flows through to reach its destination. Example: A battery is a voltage source and an electrical wire is the conductor.
What is Difference Between Current Source and Voltage Source?
A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).
