Question

If R1=2ohm and R2=4ohm find resultant resistance

Answer 1

Answer: Answer could be either 6ohm or 3/4 ohm

Explanation: Here's your answer, but next time mention whether resistors are in parallel or series combination...

When in parallel combination

R = 1/r1 + 1/r2

1/2 + 1/4

3/4 ohm

When in series combination,

R = r1 + r2

2 + 4

6 ohm .
