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
