1. Ohm’s Law

2. Summarizes the relation among the current, voltage, and resistance. The current is directly proportional to the voltage, and inversely proportional to the resistance. If the resistance of a circuit is constant, then the current and the voltage are proportional. Ohm’s Law

3. As the voltage increases, the current also increases. If the voltage of a circuit is constant, a greater resistance would mean less current. Ohm’s Law

4. Mathematically, Ohm’s law is stated as: Ohm’s Law where: V is voltage in Volts (V) I is current in amperes (A) R is resistance in ohms (Ω)
