Question

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?"

Answer 1

Sample Response: If voltage in a circuit is increased under constant resistance, then current must increase because Ohm's law states that voltage and current are directly proportional.

Answer 2

Hypothesis: If the voltage increases, then the current increases because From Ohm's law,

$I \propto V$

$I=\frac{V}{R}$

Ohm's law states that current is directly proportional to voltage and inversely proportional to resistance. If the resistance is kept constant, then with the increase in voltage, the current increases. If the Voltage applied is constant, then with increase in resistance, the amount of current flowing decreases.
