Answer 1

$\huge{\underline{\underline{\red{\sf{Answer :}}}}}$

Given :

Three resistances are of 3 Ω .

________________________

To Find :

Minimum Equivalent resistance obtained

________________________

Solution :

If we need minimum equivalent resistance put them in series. So,

• Min Resistance = 1/3 + 1/3 + 1/3

• Min Resistance = 3/3

• Min Resistance = 1

✪ Minimum Resistance = 1 Ω ✪

________________________________

And similarly for maximum resistance connect them in series.

• Max Resistance = 3 + 3 + 3

• Max Resistance = 9

✪ Maximum Resistance is 9Ω ✪
