Activity 2 — Ohm’s Law
In the following simulation, you can explore Ohm’s Law by varying the parameters ΔV and R to see how the current responds.
As you change the value of the battery voltage, how does this change the current through the circuit and the resistance of the resistor? If the current or resistance remains constant, why do you think that is?
