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. Assume the current \(I\) is constant (since questions 6 - 8 likely had a fixed - current scenario).

Step2: Analyze when resistance decreases

If \(I\) is constant, and \(R\) decreases (\(R_20\), \(V_2

Step3: Analyze when resistance increases

If \(I\) is constant, and \(R\) increases (\(R_2 > R_1\)), then \(V_2=I\times R_2\) and \(V_1=I\times R_1\). Since \(I > 0\), \(V_2>V_1\).

Answer:

When the resistance decreases (assuming constant current), the voltage required in the circuit decreases. When the resistance increases (assuming constant current), the voltage required in the circuit increases.
