What is the effect of internal resistance of the source to its output voltage?
(a) It reduces the amount of current.(b) Any current that does pass the resistor will lose some power; this lost power is converted to heat in the resistance.AnswerInternal resistance acts to reduce the terminal voltage of the voltage source when it supplies a load. This is due to the internal voltage drop caused when the load current passes through the internal resistance of that source. The greater the load, the lower the resulting teminal voltage.By definition, a voltage source's electromotive force is equal to the sum of the voltage drops, including the internal voltage drop, of the circuit supplied.
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.
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.
What is the incoming voltage from the current source to the transformer called?
the incoming voltage from the current source to the transformer is called primary voltage.....
How the current are related to the power supplied by the source?
Power (watts) is voltage times current.
What is controlled voltage?
RPS is only the voltage& power controlled device. it can only used for set the input for our wish A device which can change its output according to the voltage supplied to it is called a voltage controlled device.ex. a voltage controlled current source,or a field effect transistor. In a voltage controlled current source the output current changes as the voltage supplied to it changes.
What do you understand by electric current?
electric current is the flow of electrons due to external energy (emf) supplied by the voltage source.
What is difference between ideal current source and practical current source?
Internal resistance. The ideal current source has no internal resistance in parallel with it (if it was set to supply no current it would act as an open circuit), and all the current it supplied would have to flow through its load (even if the load was an open circuit, in which case the voltage across the current source would be infinite). A real current source has the practical limitation that it must have an internal resistance in parallel with it, therefor some of the current it supplied is bypassed through that internal resistance and never reaches the load (if the load was an open circuit, then all the current supplied is bypassed and the resulting voltage drop across the internal resistance limits the voltage across the current source).
Is diode voltage controlled device?

How do you find the branch current in parallel circuit?
For each individual branch, you can use Ohm's Law - just divide the voltage by the resistance.
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).
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 is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
How could you calculate the resistance of a circuit?
A variety of techniques can be used. Node-Voltage and Mesh-current (or Loop-current) methods, for example. See related link for examples. If there is a single voltage source in the model, then find the current supplied, and Resistance = Voltage/Current. {R = V/I} You could simulate/ model the circuit on a computer then apply the power profile and a current value will be calculated. Or if you have the circuit working, Place an amp meter into the circuit and measure the current. V/i = resistance.
How will you convert a open current circuit to a open voltage circuit?
