Answer

Answer:

Less electric charge would flow in the circuit.

Explanation:

Step1: Recall Ohm's Law

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

Step2: Analyze resistance change

Assume resistance $R$ of the circuit remains constant (since it is mainly determined by the components in the circuit and not directly by the battery voltage change).

Step3: Analyze voltage - current relationship

When voltage $V$ decreases from 9 volts to 1.5 volts (a decrease in $V$), according to $I = \frac{V}{R}$, with $R$ constant, the current $I$ decreases.

Step4: Relate current to charge flow

Current $I=\frac{Q}{t}$, where $Q$ is electric charge and $t$ is time. For a given time $t$, if $I$ decreases, then the amount of electric charge $Q$ that flows in the circuit decreases.
