Current Electricity

  1. n equal resistors are first connected in series and then connected in parallel. What is the ratio of the maximum to the minimum resistance ?​​
    1. n
    2. 1/n² ​
    3. n² ​
    4. ​1/ n
Correct Option: C

In series, Rs = nR

In parallel,1 = 1 + 1 + ... n terms
RpRR

∴ Rs/Rp = n² /1 = n²
