Question

You are given 10 resistor 2N2 each. a. What is the value of maximum of maximum and minimum resistance that can be obtained by combining them? b. How will you connect these resistors to get the above mentioned resistances.​

Answer 1

Maximum resistance can be obtained when the resistance are connected in series and minimum resistance can be obtained when the resistances are connected in parallel.

Rseries=R+R+R+...=nR.

Rseries=R+R+R+...=nR.Rparallel=R1+R1+R1+...=nR.

Therefore, RparallelRseries=nRnR=n2.

Therefore, RparallelRseries=nRnR=n2.Hence, he ratio of the maximum to minimum resistance that can be obtained by combining them is n

Answer 2

Explanation:

Minimum resistance can be obtained by combining them in parallel combination and maximum can be obtained by combining them in series combination.
