3. 22ohm
4. 1ohm
Make a Solution.....​

Answer 1

Answer: 2ohm

Explanation: 1/R = 1/4 + 1/6 + 1/12

= 6/12 = 1/2

So R= 2 ohm .

Answer 2

Answer:

the equivalent resistance is

$\frac{1}{r} = \frac{1}{4} + \frac{1}{6} + \frac{1}{12} \\ = > \frac{1}{r} = \frac{3 + 2 + 1}{12} \\ = > r = \frac{12}{6} \\ r = 2 \: \: ohm$
