When resistors are connected in series, we can be certain that:
a) the same current flows in each one.
b) the potential difference across each is the same.
c) the power is dissipated in each is the same.
d) more than one of the given answers is true.

A) the same current flows in each one.

Explanation:

When resistors are connected in series, Ohm's law states that the current flowing through each resistor is the same. Since it is similar to Ohm's law for a single resistor, except that the series resistors appear as a sum. Then, the total resistance of a series circuit is equal to the sum of the individual resistors.
