Circuit open then R is high.

Circuit close then R is low.

Zero resistance: Short circuit.

Infinite resistance: Open circuit.

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.

KOUSHIK MONDAL said:   9 years ago
The resistance of short circuit is zero. So the correct answer is (B).

Atul said:   9 years ago
At the time short resistance is very low approximately zero. So answer is correct i.e. B Shorten.

Guys I'm confused, what is the real answer on that question?

Raju said:   10 years ago
When circuit is said to be short R=0 for ideal, are is small value near to zero in practicals circuit. So that ohmmeter will show near to zero value instead of zero.

In case of ohmmeter, when the shot circuit condition than current pass maximum value after than circuit burn and current value will be zero this causes indicator is goes from close to zero.

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