Hypothesis: If the voltage in a circuit is increased, then the current will also increase, because according to Ohm's Law (V = IR), when voltage (V) rises and resistance (R) remains constant, the current (I) must increase to maintain the relationship represented in the equation. This demonstrates how changes in voltage directly affect the amount of current flowing through an electric circuit.
Write a hypothesis about the effect of increasing voltage on the current in the circuit. Use the
"if . . . then . . . because . . ." format and be sure to answer the lesson question: "How do changes in voltage or resistance affect current in an electric circuit?"
