Ohm's Law and Resistance. 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.

Answer:

a) Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

b) Ohm's law: The current flowing through a conducting wire(I) is directly proportional to the potential difference applied(v) across it, at a constant temperature.

or, at constant T.

[R: Resistance at temperature T].
