Question

Two resistors, 10-ohms and 100-ohms are connected in parallel, approximately, what is the total resistance?

Select one:

a. 50 ohms

b. 100 ohms

c. 90 ohms

d. 10 ohms​

Answer 1

B- is the answer 100 ohms

Answer 2

Answer: D

Explanation:

Total Resistance in Parallel Formula: 1/[(1/R1] + (1/R2)... + (1/Rn)]

Given: 10 ohms and 100 ohms in PARALLEL.

Therefore:

1/[(1/10 + 1/100)]

= 9.0909 ohms

≈ 10 ohms.
