The colour code for a carbon resistor of resistance $$0.2 \mathrm{k} \Omega \pm 10 \%$$ is

Each resistance in the given cubical network has resistance of $$1 \Omega$$ and equivalent resistance between $$A$$ and $$B$$ is

$$I-V$$ characteristic of a copper wire of length $$L$$ and area of cross-section $$A$$ is shown in figure. The slope of the curve becomes

The readings of ammeter and voltmeter in the following circuit are respectively
