Question
- based on questions 6, 7, and 8, what happens to the voltage required in a circuit as the resistance decreases? increases?
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_2 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 \(I > 0\), \(V_2>V_1\).Step3: Analyze when resistance increases

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.
