Canadian Electrical Engineering Formula Calculator

Common electrical formulas for Canadian engineers, electricians, technicians, and industrial maintenance teams.

Note: These calculators are for quick engineering estimates. Always verify final designs against the Canadian Electrical Code, CSA standards, utility requirements, equipment ratings, and project specifications.

1. Formula Reference

Topic	Formula	Use
Ohm's Law	V = I × R	Voltage, current, and resistance calculations.
DC Power	P = V × I	DC circuit power in watts.
Single-Phase AC Power	P = V × I × PF	Real power for single-phase AC loads.
Three-Phase AC Power	P = √3 × VL × IL × PF	Real power for three-phase systems.
Apparent Power	S = V × I or S = √3 × VL × IL	Single-phase or three-phase kVA calculation.
Energy	E = P × t	Energy consumption in kWh.
Transformer Ratio	Vp / Vs = Np / Ns	Primary and secondary voltage relationship.
Voltage Drop	VD% = VD / V × 100	Percentage voltage drop check.
Power Factor	PF = P / S	Real power divided by apparent power.
Motor Synchronous Speed	Ns = 120 × f / poles	Motor speed estimate. Canada uses 60 Hz.
Reactance	XL = 2πfL, XC = 1 / (2πfC)	Inductive and capacitive reactance.
