Question

Calculate the equivalent resistance of the circuit given below:

Answer 1

Answer:

Explanation:

first two are in parallel so ,

1/12 + 1/6 ==1/r

1+2/12 = 3/12 ==1/r

= 1/4 == 1/r

r = 4 ohms

the next is in series so,

4+5=9 ohms

the third is in parallel so

1/r == 1/4 + 1/8

1/r = 2+1/8

1/r= 3/8

r=8/3

r= 2.67 ohms

adding all we get,

2.67 + 9

11.67 ohms
