How you can take that resistor value as 3.3k?

Please explain the answer in detail.

If 1k is shorted, the current would just flow through it and to the remaining resistors, thus a voltage drop would have occurred.

If 4.7k is shorted, there would still be reading since there would still be a voltage drop in the 2.2k, the same concept applies if 2.2k is shorted there would have been reading since there would be a voltage drop in the 4.7k resistor.

If 3.3k is shorted, the current entering the node from the 1k resistor would go to the shorted circuit and there would be no drop across 4.7k and 2.2k since it has a higher resistance and is connected in parallel with the 3.3k. (Always remember that the current always find the path of least resistance).

If one 1kilo ohm resistor then no current flow.

So, the answer is option 1.

If one 1kilo ohm resistor then no current flow.

So, the answer is option 1.

If 3.3k is shorted then all current will flow through it (as current takes path with minimum resistance).

Hence no current flow through 2.2k resistor and no voltage drop across it.

There are possibility of two branches short having res. 2.2k & 3.3k because both voltmeter connected to these branches shows 0v. So I think we can not say that only 3.3k res is short. If any one know please reply me. I doubt that answer may be wrong if there is any one who can solve this doubt please reply me.

Voltage take a path always minimum load if we short 3. 3 k than voltage take that path so in all branch is 0 indicate.

please any one can tell me answer with explanation?
