Infinity
3000 ohm
The best insulation to use for bathroom walls is closed-cell spray foam insulation. It provides a high level of moisture resistance and thermal insulation, making it ideal for bathrooms where humidity levels are high.
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
infinity- so that all the voltage is measured across the component instead of losing some in voltometer circuitry
zero
An ideal superconductor has exactly zero losses, thus resistance is zero.
It depends completely on the application
internal resistance is always infinite in ideal current source .the internal resistance is in shunt with current source
friction, imperfect insulation
There is no single ideal ratio.
