Question #309a8

Answer 1

Here is a small addition to Alessandro's excellent answer...

Explanation:

If we extend the analysis provided by Alessandro to `n` resistors in parallel, the general expression will be:

`1/(R_T) = 1/(R_1) + 1/(R_2) + ... + 1/(R_n)`

Where `R_T` is the (total) equivalent resistance of the `n` resistors in parallel.
