The effective resistance of a parallel connection that consists of four wires of equal length, equal area of cross-section and same material is \(0.25\,\Omega .\) What will be the effective resistance if they are connected inseries?
1 \(0.5\,\Omega \)
2 \(1\,\Omega \)
3 \(4\,\Omega \)
4 \(0.25\,\Omega \)
Explanation:
For parallel connection \({R_P} = \frac{R}{n} = 0.25\;\Omega \) \( \Rightarrow \,\,R = 1\;\Omega \,(n = 4)\) For series connection \({R_s} = nR = 4 \times 1 = 4\,\Omega \)

Assertion : In the following circuit the net resistance between points \(A\) and \(B\) is \(r\). Reason : All the resistance are in parallel to each other.
1 Both assertion and reason are correct and reason is the correct explanation of assertion.
2 Both assertion and reason are correct but reason is not the correct explanation of assertion.
3 Assertion is correct but reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Let \(C\) and \(D\) be two points on the circuit The circuit can be redrawn as It is a wheatstone bridge \({r_{eq}} = r\) All the resistors are not in parallel. So option (3) is correct.
