Formulas
Power from Voltage & Current:
P = V × I
Where: P = power (W), V = voltage (V), I = current (A)
Energy Consumption:
Energy (kWh) = Power (kW) × Time (hours)
Cost Calculation:
Cost = Energy (kWh) × Rate ($/kWh)
Note: Actual power consumption may vary based on device efficiency, usage patterns, and power management features. These are estimates for continuous operation.
