ELECTRICAL POWER ,[object Object],[object Object],[object Object],06/06/09 07:49 PM Power = Current × Voltage P = I × V

Understanding Power Equations 06/06/09 07:49 PM Power = Current × Voltage P = I × V Current = Power ÷ Voltage Voltage = Power ÷ Current

POWER CALCULATIONS 06/06/09 07:49 PM ,[object Object],[object Object],[object Object],[object Object],[object Object],Power = Current × Voltage P = I × V Energy transferred (E) = power (P) × time (t) (t)
