1. Ohm's Law states that for some circuits the voltage is proportional to the current. In other words, if you double the voltage, you will double the current. Which of these equations agrees with this statement of Ohm's Law? (∝ means "is proportional to".)

Voltage ∝ Current^2
Voltage ∝ Current^-1
Voltage ∝ Current
Voltage2 ∝ Current

voltage

Based on the statement of Ohm's Law, which states that voltage is proportional to current, the equation that agrees with this statement is "Voltage ∝ Current." This means that when the voltage is doubled, the current will also double.
