Please do it to me thank alot

See explanations below

Explanation:

For resistors in series, the will be added for those in parallel, we will take the sum of their reciprocal

A) 3 2ohms resistors in series

Equivalent resistance = 2 + 2 + 2

Equivalent resistance = 6ohms

B) 2 4 ohms resisstors in parallal

1/R = 1/4 + 1/4

1/R = 2/4

R = 4/2

R = 4ohms

Equivalent resistance is 2ohms

C) 4 ohms with in series with 8ohms = 4 + 8

Equivalent resistance = 4 + 8

Equivalent resistance = 12ohms

D) 4 ohms and 2 ohms in parallel is expressed as;

1/R = 1/4 + 1/2

1/R = 1+2/4

1/R = 3/4

R = 4/3

4/3 ohms in series with 6ohms

Equivalent resistance = 4/3 + 6

Equivalent resistance =4+18/3

Equivalent resistance = 22/3 ohms

which statement about this sum is true? −245+2.7
