Answer

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is $I=\frac{V}{R}$, where $I$ is current, $V$ is voltage and $R$ is resistance.

Step2: Analyze series - circuit resistance

In a series circuit, when more resistors are added, the total resistance $R_{total}$ increases because $R_{total}=R_1 + R_2+...+R_n$.

Step3: Determine current change

Since the voltage $V$ is assumed to be constant (if the power - source voltage doesn't change), and $I=\frac{V}{R}$, as $R$ increases, the current $I$ decreases according to the inverse - relationship in the formula.

Answer:

B. The current will decrease.
