Question : 103 of 200

Marks: +1, -0

Which one of the following statement is TRUE?

The equivalent resistance in series combination is larger than the largest resistance in the combination.
The equivalent resistance in series combination is smaller than the largest resistance in the combination.
The equivalent resistence in series combination is equal to the smallest resistance in the combination.
The equivalent resistance in series combination is equal to the largest resistance in the combination.

Solution:

Req

= R_1 + R_2

The equivalent resistance in series combination is lar ger, then the largest resistance in the combination
Let

R_1 = 1, R_2 = 3

Req = 1 + 2 = 3
Req is greater than maximum value of

R_2
