كيف يعمل قانون أوم
Ohm's Law states that electrical potential force (Voltage) equals current (Amps) multiplied by resistance (Ohms). Combined with the Power law, we can describe all four parameters in a circuit.
This calculator solves for any two unknowns. Simply fill in two values you already know, and the system automatically determines the remaining constants using V = I × R and P = V × I equations.
V = I × R (Voltage = Current × Resistance)P = V × I (Power = Voltage × Current)P = I² × R (Power = Current squared × Resistance)P = V² ÷ R (Power = Voltage squared ÷ Resistance)Input at least two fields to solve.

الأسئلة الشائعة: قانون أوم
What is Ohm's Law?
Ohm's Law is a fundamental formula in electrical engineering showing the relationship between Voltage (V), Current (I), and Resistance (R). It states that current is directly proportional to voltage and inversely proportional to resistance.
How do you calculate power from voltage and resistance?
Use the formula Power (Watts) = Voltage² ÷ Resistance (P = V² ÷ R). For example, a 12V bulb with 6 Ohms of resistance draws 12² ÷ 6 = 24 Watts of power.
