Question

1. based on questions 6, 7, and 8, what happens to the voltage required in a circuit as the resistance decreases? increases?

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is $V = IR$, where $V$ is voltage, $I$ is current and $R$ is resistance.

Step2: Assume constant current

If the current $I$ in the circuit is held constant (not given otherwise in the problem - context), when $R$ decreases.

Step3: Analyze the change in voltage

From $V = IR$, if $I$ is constant and $R$ decreases, then $V$ (voltage) will decrease proportionally.

Answer:

The voltage decreases.
