Question

How will you convert a given set of resistors so that the equivalent resistance is increased. give reason for your answer

Answer 1

in a series connection...... the equivalent resistance increases.....

say you have 3 resistors.....of 2ohm 4ohm 8ohm....
and you've to find the equivalent resistance.....

let's do it first in parallel combination.....
1/R= 1/R1 + 1/R2 1/R3
R =8/7
R=1.14ohm.....

while in case of series connection.......
it will be 14ohm.....

and now you can see that resistance in series connection is more thanin parallel connection...
that's it
