Problem:
In a series connection of resistors the total resistance is equal to the sum of the individual resistances, whereas in a parallel connection the reciprocal value of the total resistance is equal to the sum of the reciprocal values of the individual resistances. The figure shows an example:
Answer:
Solution:
Altogether, there are 10 possibilities to construct a circuit diagram with four resistors, but one value of resistance occurs twice:
