Questions
Two resistances are joined in parallel whose resultant 6/5 ohm. One of the resistance wire is broken and the effective resistance becomes 2 ohm. Then the Resistance in ohm of the wire that got broken was
detailed solution
Correct option is D
Let the resistance of broken wire be R1The other resistance is 2 Ω. The resistance of parallel combination is 6/5.1R=1R1+1R256=1R1+12 or 56−12=1R1or 13=1R1 or R1=3ΩTalk to our academic expert!
