Question

The figure given below shows three
resistors :
622
612
212
Their combined resistance is :
(a) 1-22
5
7
(b) 1422
- 2
1​

Answer 1

Answer:

7.5 or 15/2

Explanation:

Parallel : 1/R' = 1/6 + 1/2

                     = 2/3

  Therefore...R' = 3/2

Series : R total = R' + 6

                        = 3/2 + 6

                        = 15/2 or 7.5

Hence the equivalent resistance of the system is 7.5 ohm.
