Question

find the net resistance between points B and C in the combination of resistance as shown in figure​

Answer 1

series combination= 10+10=20
parallel combination= 10+20/200=30/200=3/20
series combination= 3/20+10+10=3+200+200/20=403/20ohm

Answer 2

series combination= 10+10=20

parallel combination= 10+20/200=30/200=3/20

series combination= 3/20+10+10=3+200+200/20=403/20th ohm. Thanks guys
