Ohm's law defines the relationship between the voltage, current, and resistance in an electric circuit: I = V / R. The current is directly proportional to the voltage and inversely proportional to the resistance.
Thanks George. Electrical resistance exacts a voltage drop as the price for allowing electrical current to flow through the resistance. The use of the term resistance implies that the current flow will be in phase with the voltage across the resistor and that the current flow will be proportional to the voltage drop.hanks George.
