Question 142 of 380

A current of 6A6A enters one corner PP of an equilateral triangle PQRPQR having 33 wires of resistance 2Ω2\Omega each and leaves by the corner R.R. The currents i1{i}_{1} in ampere is

Show answer and solution

Answer: 2

For parallel combination, current divides in the inverse ratio of resistance.
iPQ=26×6A=2A{i}_{PQ}=\dfrac{2}{6}\times 6A=2A.
