Detailed explanation-1: -The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.
Detailed explanation-2: -Ohm’s Law Equation : V = IR, where V is the voltage across the conductor, I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current.
Detailed explanation-3: -Ohm’s law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm’s law is V=IR.
Detailed explanation-4: -One way Ohm’s Law can be stated is: “a current flowing through a conductor is directly proportional to the voltage, given the temperature of the conductor remains constant". Therefore, if the resistance is kept constant, then doubling the voltage doubles the current.
Detailed explanation-5: -As voltage in a circuit increases, current increases but the resistance to the flow of current remains constant. The relationship among voltage, current, and resistance is described by Ohm’s law V= IR.
