Question

Three resistances 10, 20 and 30 are given to form an electric circ
minimum possible effective resistance using them is​

Answer 1

Explanation:

resistors in series = r1 + r2 + r3 +...... + Rn

resistors in series = 60 ohm

so total resistance is 60 ohm

Answer 2

Answer:

when all the resistances are connected in parallel then minimum effective resistance is obtained.

Explanation:

When all resistances are connected in parallel then the effective or equivalent resistance is smaller than the smallest individual resistance.
