Circuit open then R is high.
Circuit close then R is low.
Circuit close then R is low.

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.

@All.
V is directly proportional to R.
i.e V=IR the increase in V increases in R and vice versa.
V is directly proportional to R.
i.e V=IR the increase in V increases in R and vice versa.

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

All resistance are zero that is current is no flow through the circuit then circuit is short circuit then answer is B.

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

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