Question

Six resistance of 112 each are connected to form a hexagon ABCDEFA. Calculate the resistance
offered by combination if the current enters at A and leaves at D.
​

Answer 1

Answer:Similarly equivalent resistance R2 of the group (AF, FE, ED)

= 1Ω + 1Ω + 1Ω = 3Ω

As the two groups are in parallel, we have

1/R = 1/R1 + 1/R2 = 1/3 + 1/3 = 2/3

Where R is the equivalent resistance of the whole combination.

∴ R = 3/2Ω or 1.5Ω
