It is not an ideal resistor so r is approximately equal to zero but not exactly zero when short circuit.

When high current pass through the ohmmeter its start working and it is shorted then it shows zero.

When the circuit is shorted high current flow through the circuit. So the resistance value is zero.

Ohmmeter measures resistance, so if it measures zero then resistance is zero, which is for a wire.

Its option B, because short circuit has zero resistance and open circuit has infinite resistance.

At the time short resistance is very low approximately zero. So answer is correct i.e. B Shorten.

The resistance of short circuit is zero. So the correct answer is (B).

I think if analog meter directly goes to zero and MCB will break down.

Zero resistance: Short circuit.

Infinite resistance: Open circuit.
