A wire has a resistance of \(6 \Omega\). It is cut into two parts and both half values are connected in parallel. The new resistance is
- A \(12 \Omega\)
- B \(1 . \mathrm{\Omega}\)
- C \(3 \Omega\)
- D \(6 \Omega\)
Answer & Solution
Correct Answer
(B) \(1 . \mathrm{\Omega}\)
Step-by-step Solution
Detailed explanation
Given, resistance of the wire, \(R=6 \Omega\) When it is cut in two equal parts, then resistance of the cach part of wire is given by \[ r=\frac{R}{2}=3 \Omega \] \((\because R \propto \bar{l})\) Now, these new resistances are connected in parallel wmbination. The equivalent…
