Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to its resistance.

• Ohm's law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.

• It can be used to calculate any one of the three variables if the other two are known.

• For example, if a circuit has a voltage of 12V and a resistance of 4 ohms, the current flowing through it would be 3A (I = V/R).

Electricity is the flow of electric charge through a conductor.

• Electricity is a form of energy that powers various devices and systems.

• It is generated by the movement of electrons through a conductor.

• Electricity can be produced by various means such as chemical reactions, electromagnetic induction, and photovoltaic cells.

• Examples of electricity sources include batteries, power plants, and solar panels.
