Question

If each resistance is 1 ome resultant resistance at B is if there are two parral and one series connection of resistors

Answer 1

R1 equals to 1 ohm

R2 equals to 1 ohm

1/RP=1/R1+1/R2

=1/1+1/1

=1+1

=2ohm,is your ans

Answer 2

Resistance of series= 1+1= 2Ω

Resultant resistance= 1*2/1=2/3=0.667 Ω
