Three resistors having the same resistance value are wired in parallel. how does the equivalent resistance compare to the resistance value of a single resistor?

The equivalent resistance is less than the resistance of a single resistor

Explanation:

Imagine three 3-ohm resistors connected in parallel.

1/Req= 1/R + 1/R + 1/R

1/Req= 1/3 + 1/3 + 1/3

equivalent resistance is [3(1/3)^-1]=1ohm

This is less than the individual resistance of each of the original three ohm resistors. Hence the answer.

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.

explanation:

it doesn't. it was imagined up in the middle ages.
