What is independent voltage source?
An independent voltage/current source is an idealized circuit component that fixes the voltage or current in a branch, respectively, to a specified value. If that branch is an independent voltage source, then we know that the voltage across the branch has a fixed value, but the current is free.
Which is the resistance independent of source voltage?
The internal resistance of an ideal voltage source is zero; it is able to supply or absorb any amount of current. The current through an ideal voltage source is completely determined by the external circuit.
Can a voltage regulator be used as a constant current source?
In his video [Afroman] describes how the LM317 can be used to regulate current rather than voltage to provide a constant current source under varying load. This can useful for a number of applications including driving LEDs and laser diodes.
How is a voltage regulator used in an integrated circuit?
An integrated circuit voltage regulator. A voltage regulator is a system designed to automatically maintain a constant voltage. A voltage regulator may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design,
Can a shunt resistor be used as a current regulator?
The hardware outputs a variable voltage depending on the voltage drop across the shunt resistor. Knowing this means that many of use will instinctively think of using a constant voltage source and a well chosen resistor to turn a small voltage regulator into a current regulator.
When do you need a voltage regulator for a generator?
Voltage regulator for generators. Generators, as used in power stations, ship electrical power production, or standby power systems, will have automatic voltage regulators (AVR) to stabilize their voltages as the load on the generators changes.
