What is a common source for a voltage?

Batteries provide a voltage difference.


What is the difference between voltage forward voltage and voltage drop?

Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.


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.


Why do you always use voltage source in lab not current source?

Current is created by voltage (potential difference), not the other way round. It's the voltage - or 'push' - that is making your current move.


Difference between voltage and emf?

'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.


Why peak voltage of the load is smaller than the voltage from the transformer output?

The voltage appearing across a load is always smaller than the no-load voltage of any voltage source -e.g. batteries, generators, or transformers. In simple terms this is because all these voltage sources have internal resistance or impedance which results in an internal voltage drop when the source delivers a load current. The resulting voltage, therefore, is always the difference between the no-load voltage and the internal voltage drop. A measure of the difference between a source's no-load and full-load voltage is termed its 'voltage regulation'.


The voltage of a given common source JFET amplifier is depend on what?

amplification factor


How much signal voltage should be measured at the bypassed source of a common source amplifier?

the same amount as the drain


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).


What is source of voltage?

Energy is the source of voltage


What is the difference between the terminal voltage and the source voltage?

the source voltage is the voltage that measured exactly after the voltage source , but the terminal voltage is the voltage that measured in the load terminals , which equal to the source voltage minus the drop voltage on the transmission line .


What is practical voltage source?

in case of ideal voltage source we consider the internal resistance to be zero.but in practical,every battery has some internal resistance then if you connect a load resistance across the terminals of that source,the net potential difference's across the voltage source will be a function of external resistance connects it won't give constant voltage across it's terminals.
