Identify the formula that represents Ohm's law.

V = A Ω

The correct answer is option 4. V = A Ω.

Ohm's Law \((V = IR)\) is as fundamentally important as Einstein's Relativity equation \((E = mc^2)\) is to physicists. When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or \(V = A x Q\). Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. One of the most basic and important laws of electric circuits is Ohm's law.

Archimede's Principle states that a body immersed in a fluid experiences an up thrust equal to the weight of the fluid displaced, and this is fundamental to the equilibrium of a body floating in still water.

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it.
