Why Internal Resistance Of Current Source Is Infinite
Why Internal Resistance Of Current Source Is Infinite. All of the current from the current source (100ma) flows through the 8ω resistor load. We therefore conclude that the internal resistance of an ideal source is zero.

The internal resistance must become very high to deliver maximum current. To say that an ideal current source has infinite internal resistance is to say that the current through is independent of the voltage across. 2.92 (a) for conversion into an equivalent current source.
The Voltage Across An Ideal Current Source Is Completely Determined By The Circuit It Is Connected To.
The current will always want to escape out of its infinite resistance to a lower resistance. Practically current sources do not have infinite resistance across there but they have a finite internal resistance. Asked oct 30, 2020 in physics by saavya (51.8k points) an ideal current source has.
The Internal Resistance Must Become Very High To Deliver Maximum Current.
The voltage across an ideal current source is completely determined by the circuit it is connected to. ← prev question next question →. From another perspective, for a current source with finite internal resistance $r_s$, the load resistance is in parallel with the internal resistance and so, by current division, the load current varies with the load resistance and is.
The Internal Resistance Of An Ideal Current Source Is Infinite.
An ideal current source has a. Thus, you might say they can be ignored, i.e., replaced with open circuits, when calculating. We therefore conclude that the internal resistance of an ideal source is zero.
So For The Reason Of Having More Of The Total Current Flowing Through The Load, A Higher Internal Resistance In A Real Current Source Is Desirable (And Infinite Internal Resistance Brings You Back To An Ideal Current Source)
To say that an ideal current source has infinite internal resistance is to say that the current through is independent of the voltage across. The internal resistance of an ideal voltmeter is infinity and the internal resistance of an ideal ammeter is zero. This infinite resistance will not affect voltage sources in the circuit.
When I C = 0 , The Current Source Is An Open Circuit (No Current Through For Any Voltage Across).
So the current delivered by the practical current source is not constant and. The internal resistance of current source is the value of resistance connected across its terminal. Any current source is represented by a parallel connection of current source and resistance.
