If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor.
[SOLVED] When two resistances are connected in parallel then the equivalent resistance is 65Ω . When one of the resistance is removed then the effective resistance is 2Ω . The resistance of the wire removed will be
Two equal value resistors in parallel have a total value of 1/2 or 2.25. In parallel, the total resistance is always less than the lowest value resistance. Since the parallel resistance =2, the lower resistor must be more than 2.
Note that the equivalent resistance is always less than the smallest resistor in the parallel network so the total resistance, RT will always decrease as additional parallel resistors are added.
