Question

which of the following resistor arrangement A Or B has the lower combined resistance​

Answer 1

Answer:

A is 10ohm

Explanation:

Resistance of arrangement A is 10 ohm. Combined resistance of arrangement B is caculated as follows: 1/R = 1/10 + 1/1000 = (100+1)/1000 R = 1000/101 = 9.9 ohm Therefore, arrangement B has lower combined resistance.Read more on Sarthaks.com - https://www.sarthaks.com/127327/which-of-the-following-resistor-arrangement-a-or-b-has-the-lower-combined-resistance

Answer 2

Answer:

Explanation:

1/rp=1/r1+1tr2

1/rp=1/10+1/1000=1000/101

Rp= 9.9ohm

Rs=10ohm

10ohm>9.9ohm

So resistor in parallel (i.e) B has lower resistance.
