It depends completely on the application
3000 ohm
internal resistance is always infinite in ideal current source .the internal resistance is in shunt with current source
ideal ammeter has zero internal resistance
The resistance of an ideal oscilloscope probe is infinity.
if any thing is ideal then that has no any resistance
every inductor has some resistance. In circuit diagram, ideal inductor is shown in series with a resistor(value being equal to coil's resistance) to make analysis easy.
infinity- so that all the voltage is measured across the component instead of losing some in voltometer circuitry
zero
Current source means current generator for a circuit. An ideal current source gives all current to the circuit, but practically a current source does n't give all current to the circuit, instead, a source resistor is connected in parallel to the current source to indicate the current drop.
An ideal superconductor has exactly zero losses, thus resistance is zero.
The number of ohms is, precisely, the value of the resistance.
