Questions
Five resistances are connected as shown in fig. The effective resistance between the points A and B is
a
10/ 3 Ω
b
20 /3 Ω
c
15Ω
d
6 Ω
detailed solution
Correct option is A
Resistance between, A and B for upper pa = 2+3= 5ΩResistance between A and B for lower part = 4+6= 10ΩAs bridge is balanced, the two resistances are in parallel and the resistance 7Ω is ineffective. Thus 1R=15+110=310R=(10/3)ΩTalk to our academic expert!
