Question

Question 1: What happens to the batteries in the circuit when you move the Voltage slider up and down?(3 points)

They move around the circuit.

More batteries stack up as voltage increases; fewer as it decreases.

They disappear completely.

They change color but stay the same number.
Question 2: What is the maximum voltage you can set using the Voltage slider?(2 points)

4.5 V

15 V

9.0 V

0 V
Question 3: What is the minimum voltage you can set using the Voltage slider?(2 points)

15.0 V

-4.5 V

9.0 V

0.1 V
Question 4: When you increase the voltage (with resistance fixed), which other variable in the equation V = I × R is most directly affected?(2 points)

Resistance decreases.

Current increases.

Voltage stays the same.

Current decreases.
Question 5: Why does current change when voltage changes (while resistance stays the same)?

What is Ohm's Law? Explanation, Formula and Solved Example

(2 points)

Current only depends on resistance, not voltage.

The batteries shrink.

The resistor gets hotter and blocks current.

Higher voltage pushes more electrons through the circuit (like more pressure in a hose).
Question 6: After clicking Reset, when you increase the Resistance slider, what do you observe about the resistor and current?(2 points)

The resistor gets larger in size; current decreases

The resistor gets larger in size; current increases.

The resistor shrinks; current increases.

Nothing changes.
