Question

3identical resistance are first connect in series and then in parallel find its reatio to first connection to second ​

Answer 1

Answer:

Ratio of first connection to second connection is 9:1.

Explanation:

In first case

3 identical resistance are connected in series connection.

Then,

(Req)1 = nR

(Req)1 = 3R

Here,

n is the number of residence

In second case

3 identical resistance are connected in parallel connection.

Then,

(Req)2 = R/n

(Req)2 = R/3

Here,.

n is the number of residence.

Ratio = (Req)1/(Req)2

Ratio = 3R/R/3

Ratio = (3R × 3)/R

Ratio = 9R/R

Ratio = 9

Hence,

Ratio of first connection to second connection is 9:1.
