Question

You have been provided with four 100 ohm
resistors each with a tolerance of 2%. The
number of ways in which these can be combined
to have different equivalent resistances is
(a) seven different combinations and seven
different equivalents
(b) eight different combinations and seven
different equivalents resistances
(c) nine different combinations and eight
different resistances
(d) ten different combinations and nine
different resistances

Answer 1

There are seven different combinations and seven  different equivalents  in which these can be combined  to have different equivalent resistances.

Option (A) is correct.

Explanation:

You have been provided with four 100 ohm  resistors each with a tolerance of 2%. The  number of ways in which these can be combined  to have different equivalent resistances is

(a) seven different combinations and seven  different equivalents

(b) eight different combinations and seven  different equivalents resistances

(c) nine different combinations and eight  different resistances

(d) ten different combinations and nine  different resistances

There are seven different combinations and seven  different equivalents  in which these can be combined  to have different equivalent resistances.
