What does the power rating of an electrical appliance mean?
what is the power rating of energy
Why must not you replace a fuse in a plug with an iron nail even the appliance still work?
A fuse is specifically rated to a certain amount of power. When this is exceeded the fuse 'melts' and will not allow the power limit to be over extended. A nail will allow the appliance to work but offers no protection.
An appliance plug can be distinguished from other plugs by its?
permanent attachment to an appliance An appliance plug may have a differently shaped plug, in order to prevent it from being plugged into an ordinary electrical outlet (one with the wrong voltage or power rating).
Where can you find the power rating of an electrical appliance?
Normally the power rating of an electrical appliance can be found on its 'Rating Plate' or, if there isn't one, use the following formula W = A x V, where W = watts, A = current and V = voltage.
What happens when capacitor KVAr rating is much bigger than the required rating?
You end up with a leading power factor. The Kvar meter will run backwards.

What is maximum power rating?
Maximum power rating describes the maximum power at which a device can operate without reaching an excessive temperature. For example, in the case of a resistor, if its maximum power rating is exceeded, then it may burn out.
What does the power rating for an appliance tell us?
How much energy it uses
Is it true that a label on a new appliance shows its power rating?
Most new appliances have a power rating label on them. The Energy Star label is an indication that the appliance is more energy efficient than others and will tell you how much the appliance will cost you to run. Appliances that do not have an Energy Star label are not a good investment.
What is the difference between va and watt rating of an electrical appliance?
Depends on the appliance, and in most cases, it does not matter. For a purely resistive appliance, such as a kettle, or a toaster, the two should be the same. Certain devices such as computers and other electronics will consume reactive power, which is measured by the VA rating. The Watt rating measures only real power. In residential settings, you will not be billed for reactive power, and so you do not need to worry about the VA rating. However, the VA rating is the "true" power required by the device, so if you are planning to hook it up to a generator or UPS, you will need to be able to provide at least that much power.
How many appliances can work using 5kW?
That depends entirely on the power rating of each appliance !
Can you run a three phase appliance on 240 volt power supply?
No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
If you know the power rating of an appliance and the voltage of the line it is attached to you can you calculate the current used by the appliance?
If I understood your question correctly, 'If you know the power rating of an appliance and the voltage of the line it is attached to, can you calculate the current used by the appliance?' You are looking for this equation: I = Current (Amps) P = Power Rating (Watts) V = Voltage (Volts) I = P/V This equation is useful when calculating the fuse rating for an appliance. For example, and appliance rated at 2400 watts, supplied with 240 volts has a 10 amp maximum. I = 2400/240 however, when it comes to paying for electricity, the energy is measured in units, which can be found using the equation: P = Power (kW) t = Time (Hours) Energy Used (Units) = Pt for example, an appliance rated at 2 kW used for 3 hours, uses 6 units of energy. Units = 2*3
