Sorry, but I'm not really sure what you mean by that.rl.bhat said:Since the ammeter reads zero, that branch can be taken as short circuit or open circuit.
Now apply equivalent resistance formula to find R.

Equivalent resistance is the total resistance of a circuit when multiple resistors are connected in either series or parallel. It represents the combined effect of all the resistors in the circuit.
To calculate equivalent resistance for resistors in series, you simply add up the individual resistances. The formula is: Req = R1 + R2 + R3 + ..., where Req is the equivalent resistance and R1, R2, R3, etc. are the individual resistances.
To calculate equivalent resistance for resistors in parallel, you use the formula: 1/Req = 1/R1 + 1/R2 + 1/R3 + ..., where Req is the equivalent resistance and R1, R2, R3, etc. are the individual resistances. Then, you take the reciprocal of the sum to get the equivalent resistance.
In series circuits, the equivalent resistance is always greater than the individual resistances, as they add up. In parallel circuits, the equivalent resistance is always less than the individual resistances, as they are inversely proportional.
Equivalent resistance is important because it helps us analyze and understand the behavior of complex circuits. It allows us to simplify the circuit and calculate important values such as current and voltage using Ohm's Law.
