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 formula do you use to determine the amount of energy used by an appliance?

Power use of an electrical appliance is calculated by finding its rating in watts. The formula is W = I x E. Watts = Amps x Volts. <<>> Power is a general term. If you want to know how much you pay to power a certain appliance you need to figure out the amperage of the appliance, (usually located on the appliance itself or in the instructions). Power companies use kilowatt hours to charge you for electricity, to figure out how many kilowatt hours your appliance uses you would need to multiply the amperage your appliance uses by .115 and that would give you the kilowatts it is using. Then you would multiply that by how many hours you use said appliance and then multiply by your cost per kilowatt hour, (found on your electric bill).


What fuse would you use if you were fitting a new plug to a 2.5kw heater assume a voltage of 120v?

To calculate the fuse rating needed, use the formula: Fuse rating = (Power of appliance / Voltage of appliance) + 0.25. For the 2.5kW heater at 120V, the calculation is (2500W / 120V) + 0.25 = 20.83A. Therefore, you would use a 20A fuse for the 2.5kW heater at 120V.


How do you get enought electricity to your new wall oven and microwave from a standard outlet?

First, determine the current necessary to operate the appliance. Read the installation manual to find out the manufacturers recommendations. If the existing outlet does not supply sufficient current to operate the appliance, you'll need to run a new wire and install a larger breaker in your main breaker panel.


How do you find out the power rating of your power supply?

You can find the power rating of your power supply by looking at the label or sticker on the unit itself. It should indicate the maximum power output in watts (W). You can also check the manufacturer's website or product manual for this information.


What should a breaker panel look like?

A breaker panel, also known as an electrical panel, typically has a metal casing with a hinged door that covers the breakers inside. Inside, you'll find rows of circuit breakers, usually labeled with what area or appliance they control. There should also be a main breaker that shuts off all power to the panel.

The rated voltage of an appliance is no guide to its power rating. To find out the power (watts), you will need to look at your washing machine's nameplate, which will indicate both its rated voltage and its rated power.


What is the equation to find the amount of energy used. By appliance?

The equation to calculate the amount of energy used by an appliance is: Energy (kWh) = Power (kW) x Time (hours). Multiply the power consumption of the appliance in kilowatts by the number of hours it's used to find the total energy consumed in kilowatt-hours.

What can you do if your gas dryer is not drying?

If it is not drying because there is no heat, the best suggestion is to call an appliance tradesman and get them to look at the problem. They will be able to check for leaks, check burner etc.. If it is an electrical problem, the same appliance tradesman should be able to find out what is wrong and they are allowed to repair the electrical fault.


How do you find the current draw of an electrical circuit if you do not know the voltage and wattage of the device?

Basically if you know the Voltage supply and the power used by an appliance then you use the formula for power which is Power = Volts x Amps. Rearrange so Amps (current) = Power / Volts If power was 2400 Watts and Volts was 240 the Current would be 2400 / 240 = 10 Amps


What is the load in a socket?

Every electrical socket has a different lost rating. If you look closely on the sockets yoke you will either find the rating or a NEMA number. If you find a NEMA number you will have to referance the NEMA chart.


How can I determine how to find a breaker in my electrical panel?

To find a breaker in your electrical panel, start by identifying the labels on the panel that correspond to different areas of your home. Then, systematically switch off each breaker one at a time while checking which area of your home loses power. This process will help you determine which breaker controls the specific area or appliance you are trying to locate.


Where can you find a list of average power consumptions of various household appliances?

Every appliance has a power consumption rating on a label somewhere. Just remember the conversion formula: Volts X Amps = Watts, then you can easily convert between amps and watts. Household voltage in U.S and Canada is 115 VAC +/- a little.

How do you find the current rating of a zener diode if the power rating is 500mw and a voltage rating of 10v?

A zener diode with a rating of 500 mW will pass 50 mA at 10 V. (Power = voltage times current)Note: The question appears mis stated, in that it states a rating of 500 MW, not 500 mW. To my knowledge, there is no zener with a rating of 500 MW.
