Question

You have three resistors of 9 ohms each. By combining them what can be (a) the highest resistance, and (b) the lowest resistance? (c) How can you combine them to get a resistanbe of 12 ohms?

~* THE ANSWER OF YOUR QUESTION IS..*~

✍✍✍✍✍✍✍✍________________________________________

the highest resistance will be obtained when they are connected in series I.e

R = 9 + 9 + 9

= 27 ohm

the lowest value of resistance Will be obtained when they are connected in parallel

I.e 1/R != 1/9 +1/9 + 1/9

R=3 ohm

(3) it is not possible to obtain 12 ohm from three restrictions of 9 ohm each.

HOPE IT WILL HELP YOU

Answer 2

hey mate ♡♡
here is your answer:-

《1》the highest resistance is obtained
when we combine. them in series

☆ 9+9+9= 27

《2》 the lowest resistance is obtained when we combine them in parallel

☆ 1/R = 1/9 +1/9 + 1/9
= 3/9
= 1/3
hence the resistance is 3

《3 》 it is not possible to combine them to obtained 12 ohm resistance

hope its helpful for you dear♡♡☆
