Question

The resistance of 0.01 ohm is connected to a resistance of one kilo ohm in parallel. The resistance of the combination will be​

Answer 1

Answer:

0.01 ohm

Explanation:

when a resistance R is connected in parallel to R

′

and(R<R

′

), then the resultant resistance lies between R/2 and R. If R

′

is only slightly greater than R, the resistance is a little greater than R/2 and if R

′

is very large as compared to R, resultant resistance almost approaches the value of R.

In this case, let R = 0.01 ohm and R

′

= 1000 ohms. Here, R

′

is very large as compared to R so, resultant resistance almost approaches the value of R, that is, 0.01 ohm.

Answer 2

Explanation:

R= (r1 x r2) /r1 + r2 = ( 0.01 x 1000) /( 1000 + 0.01)

~ 10 /1000 ~0.01 ohm
