The equivalent resistance of `n` identical resistors connected in parallel si `x`. If the resistors are connected in series, the equivalent resistance would be.

Options

A. n x
B. `n^2 x`
C. `(x)/(n)`
D. `(n)/(x)`

Answer

B

Explanation

Let `R` is each resistance
`(R )/(n) = x rArr R = nx`
`R'_(eq) = nR = n.nx = n^2 x`.
