Ohm’s Law قانون أوم

Two ways to see the same relationship
طريقتان لرؤية العلاقة نفسها

I = V / R2 A = 6 V / 3 Ω
Voltage · Vالجهد
Resistance · Rالمقاومة
Current · Iالتيار

Conventional current flows from + to − through the resistor; electrons move in the opposite direction.يمر التيار التقليدي من الموجب إلى السالب عبر المقاومة؛ وتتحرك الإلكترونات في الاتجاه المعاكس.

Ohm’s Law: the water analogyAn illustrated chrome faucet supplies water through a flexible transparent hose. Voltage rotates the blue handle and changes a pressure indicator. Resistance brings the thumb and curled fingers together to narrow the hose. Bubble speed and crossing frequency represent current, calculated only as voltage divided by resistance.
