Question

What is the minimum resistance which can be made using 5resistors each of 1/5 ohm

Answer 1

Answer:

1 / 25 ohms

Explanation:

✔️To get minimum resistance we need to connect all the resistors in parallel.

Now,

✔️When 'n' resistors of equal resistance 'R' are all connected in parallel

Then,

✔️R eq = R / n

✔️Now, 5 resistors each of resistance 1/ 5 ohm are connected in parallel

So,

✔️R eq = R / n

✔️R eq = (1/5) / 5 ohms

✔️R eq = 1 / 25 ohm

Hence, the minimum resistance we can get from the given set of resistors is 1 / 25 ohms.
