Proporsionalitas

Definisi

Hubungan matematis antara dua besaran di mana rasio mereka tetap konstan (proporsionalitas langsung) atau hasil kali mereka tetap konstan (proporsionalitas terbalik).

Penjelasan

Ohm’s Law states V = IR: voltage is directly proportional to current when resistance is fixed — doubling the current doubles the voltage. Boyle’s Law (PV = constant) is an inverse proportionality: halving the volume of a gas at fixed temperature doubles its pressure. Proportionality relationships allow prediction of one variable from changes in another without solving a full equation.
