Question

.Connect two resistors of 4 Ω each in such a way to get

equivalent resistance of 2 Ω.​

Answer 1

Answer:

in parallel combination

Answer 2

Answer:

I hope this isn’t a homework problem for a class you’re taking in electronics or basic electrical theory, because Ohm’s Law is the most basic idea you’ll encounter, and that you should have encountered and memorized already.

Explanation:

For N resistors in parallel, Rtotal = 1/(1/R1 + 1/R2 _ 1/R3 _ . . . 1/Rn).

If the resistors are all identical, this reduces to Rtotal = Rn/N.

Thus in your example, Rtotal = 2/4 = 1/2 ohm.

I could expand this analysis to capacitors and inductors, but I’m betting that you’re probably not there yet,
