Electricity

Simple calculation between I, V, R, P

I = Current in Amperes (A)

V = Voltage in Volts (V)

P = Power in Watts (W)

R = Resistance in Ohm (Ω)

Alternating current (AC)

A type of electrical current that circuits and appliances in most homes utilize.

Expressed as a sine wave, the current of AC passes through zero when it changes direction, which makes it a safer electrical current.

Direct current (DC)

A type of electricity created by solar modules when solar rays hit them. This energy is converted into Alternating Current (AC) electricity to be used in our home.

Single/Three/Split phase power

  • Single-phase power is a type of alternating current (AC) in which all voltages vary in unison. Single-phase power is the most common household power circuit. It is often used to power lighting, heating, televisions, and other appliances.

  • A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the alternating current (AC) equivalent of the original Edison Machine Works three-wire direct-current system.

  • Three-phase power is a type of alternating current (AC) that ensures constant power supply. Unlike single-phase power where electrons travel through one wire, here the electrons move through three wires at slightly different times. Three-phase power is usually used by electrical grids to transfer electricity or to power industrial machinery, large motors, and other heavy loads. Essentially converting power over separate currents, out of phase with one another. Residential systems would utilize a single-phase solution.
