Voltage of electrical appliances

Before beginning any excavation in the vicinity of underground electrical lines or working in the vicinity of an overhead high- voltage electrical line, call 8to . Background: The electric power required by an electric appliance can be estimated as. CURRENT) × (the VOLTAGE across its terminals). The power of an electrical appliance can be calculated from the current that flows through it and the potential difference across it.

You can work out power using this equation: Power = voltage × current.

The Rating of an electrical appliance indicates the voltage at which the appliance is designed to work and the current consumption at that voltage.

The rating of the appliance is related the power it consumes.

Minimum wire size for hand-held or portable equipment is usually restricted by the mechanical strength of the conductors. National electrical codes prescribe wiring methods intended to minimize . A guide which includes common domestic appliances and their amps and watts power ratings as well as further information for your reference. Broadly speaking, voltage is the electrical equivalent of force and we often power electrical appliances and gadgets with far more volts than they actually . There are four matters relating to using US appliances in the UK. This means that when appliances made for use in North America . By low voltage , what do you mean? The electrical wiring in most homes previously only carried 1volts and not 125.

What You Should Know About Traveling Overseas with Electrical Appliances. Appliances built for use in North America are designed to operate on 110- 120VAC (Volts Alternating Current). Most of the worl however, operates on 220- 240VAC.

When traveling overseas, it is important to convert the voltage to match your . It turns out that the higher the voltage electricity you use, and the lower the current, the less energy is wasted in this way. So the electricity that comes . In the UK this means the 2volt mains supply. Be aware of multiphase electrical systems (see below under Large Appliance Power).

If the voltage and frequency for your device is the same as where you are travelling, then you need to worry only about the physical plug. The small difference between 110V and 120V is within the .
