📚 What is Electric Power Law?

The Electric Power Law states that Power (P) is the product of Voltage (V) and Current (I). The fundamental formula is: P = V × I

This law can be combined with Ohm's Law (V = I × R) to derive additional power formulas: P = I² × R and P = V² / R

📐 Power Law Formulas

P = V × I

Power equals voltage times current (fundamental form)

P = V² / R

Power using voltage and resistance (from Ohm's Law)

P = I² × R

Power using current and resistance (from Ohm's Law)

E = P × t

Total energy (Joules) equals power times time

V = I × R

Ohm's Law: Voltage equals current times resistance
