1.

n resistances, each of r Omega, when connected in parallel give an equivalent resistance of R Omega. If these resistances were connected in series, the combination would have a resistance in homs equal to

Answer»

`n^(2)R`
`(R )/(n^(2))`
`(R )/(n)`
NR

SOLUTION :Resistance in PARALLEL combination, `R=(r )/(n) RARR r=Rn`
Resistance in SERIES combination, `R.=nr=n^(2)R`
