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.
What else can I help you with?
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.
How do you change current into voltage?
Compute the open load voltage of the current source across its shunt resistance.This voltage becomes the voltage source's voltage.Move the current source's shunt resistance to the voltage source's series resistance.Insert the new voltage source into the original circuit in place of the current source.
What happens to current in a circuit if the voltage is halved and the resistance stays the same?
the current doubles.. explanation:V=IR hence I=V/R which means that when the supply voltage is constant ,current is inversely proportional to resistance.thus the current doubles. practically speaking when the resistance of the load(fan ,bulb,refrigerator,....) is less ,it draws more current from the source so as to balance the voltage across it.i.e; to maintain the voltage across it as constant. This answer is absolutely correct if you assume that the current comes from a pure voltage source ( voltage source with zero internal resistance). At the other extreme you could have a current source (such as a very large voltage source in series with a very large resistor), and then the current is practically independent of changes if the external resistance is changed (because the change represents a relatively minute change in the overall resistance). With appropriate circuitry it is possible to devise a situation where the current is practically independent of the changing resistance.
How will you convert a open current circuit to a open voltage circuit?
The first thing you need to know is the internal resistance of the current source, the voltage source will have the same internal resistance. Then compute the open circuit voltage of the current source, this will be the voltage of the voltage source. You are now done.
What is the maximum current that can be drawn from a voltage source?
The maximum current that can be drawn from a voltage source is dependent on the impedance of that source, the impedance of the connections to the source, and the energy available from that source.
Why an independent voltage source is made deactivated by shortening and an independent current source is made deactivated by open circuiting?
Short-circuiting an independent voltage source effectively sets its voltage to zero, deactivating it. Since current in a short circuit is maximized, this creates a situation where the voltage source cannot maintain its specified voltage. Open circuiting an independent current source prevents the flow of current, effectively deactivating it because without a complete path for current to flow, the current source cannot maintain its specified current output.
What are independent and dependent sources?
An independent source is a source that produce constant currents and voltage. Dependent sources are voltage sources that depend on a voltage somewhere else in the network.
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 is example of dependent source and independent source of voltage and current?
Boss its a circuit not a device, you can also create one of yours..... just use simple logic of voltage divider and current divider rules...-satendra.svnit@gmail.com
What is source of voltage?
Energy is the source of voltage
What is the difference between independent and dependent source?
Independent SourcesIndependent sources produce current/voltage at a particular rate that is dependent only on time. These sources may output a constant current/voltage, or they may output current/voltage that varies with time.Dependent SourcesDependent sources are current or voltage sources whose output value is based on time or another value from the circuit. A dependent source may be based on the voltage over a resistor for example, or even the current flowing through a given wire. The following sources are possible:Current-controlled current sourceCurrent-controlled voltage sourceVoltage-controlled current sourceVoltage-controlled voltage sourceDependent sources are useful for modelling transistors or vacuum tubes.
What happens if a 110V masseur is connected to 230V source?
If a 110V masseur is connected to a 230V source, the masseur will likely be damaged due to the higher voltage. The device is designed to operate at 110V, so the higher voltage will cause an overload and could potentially lead to overheating, short-circuiting, or burning out the electrical components. It is important to always use devices with the correct voltage to prevent damage and ensure safety.
How do you make electricity for a science experiment?
an electric circuit consists of a voltage source (like a battery), something to use up some of the voltage to keep it from short circuiting ( like a light bulb or a motor), and wires to connect the positive end of the battery to the light bulb or other device, then more wire to connect the other part of the bulb to the negative end of the battery.
What is independent light source?
The sun is an independent light 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).
