Question

There are n identical resister first all connected in series and then all connected in parallel.The ratio of total resistance in series to parallel will be......​

Answer 1

Answer:

n².

Explanation:

n resistors of resistance let R

so when they are kept in series total resistance is

R+R+R+R...n

=nR

when they are kept in parallel total resistance is

1/Req= 1/R + 1/R +1/R ...n

1/Req = n/R

Req = R/n

so ratio is nR/R/n

= n².

hope it helped.
