Question

Plz solve it :--

the resultant value of resistances each of value r ohms when connected in parallel is x, when these resistances are connected in series the resultant resistance is ________.

Answer 1

for parallel combination
1/Req= 1/r+1/r+.......
1/Req=n/r
x=r/n........eq 1
for series combination
Req=r +r+....
Req=nr......eq 2
put the value of n from eq 1 in eq 2
Req=r/X ×r
Req=r²/x

Answer 2

Answer:

the answer for this question is

r/4
