Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. Mathematically, it can be expressed as I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.
Boyle's Law states that the pressure of a gas is inversely proportional to its volume, when the temperature is kept constant. Mathematically, it can be expressed as P1V1 = P2V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.
