120 Volts multiplied by 1.4 Amps equals 168 Watts. This may be steady state current though so allow more for startup. Also the fridge probably does not have the pump running all of the time so figure the 'on' time compared to the 'off' time for a true average.
About 0.1 kW for a kitchen fridge.
The formula you are looking for is I = W/E.
The formula you are looking for is W = A x V.
could be up to 500 different kinds of bacteria depending on where the fridge is an the frequency of use/ users
We use electricity in many home appliances such as toasters, TV, stove, oven etc. Without electricity, we wouldn't have much fun and we'd have to cook on logs like the pioneers!We use electricity in many things in our homes: electric lights, home appliances such as toaster, microwave, fridge, tv, washer, dryer, etc.Also we use electricity in our cars (and trucks) which need the electricity stored in on-board batteries. The battery is used to supply electricity to the starter motor which first makes the engine turn so that it can run on its own fuel (gas or diesel). Electricity is then used to recharge the battery, to drive the fuel pumps - which supply the engine with more fuel from the fuel tank - to power the lights, etc.

How Long will a Mini-fridge run on a Car BatteryIt depends on the capacity [measured in Amp-Hours] of the battery, and the amount [how much Amps] of current the mini-fridge draws [uses].I have an electrically operateed cooler/warmer [looks like an "ice chest"] that plugs into the cigarette lighter, and without the engine running, it will fully discharge the battery in about two hours!!!I think that mini-fridges operate on the same principle, and thus, I wouldn't expect a car battery to hold up much longer.
Because there is much in the house that runs on electricity. Lights, fridge/freezer, the kitchen range. water heater. TV, wi-fi, aircon etc etc
minimum 230volts In formal electrical jargon, a "device" does not "use" electricity. A device is something like a switch or receptacle(outlet) that helps control or carry electricity but does not consume electricity. In the United States, voltage for home lighting and general purpose receptacles is 120v. Voltage for electrical appliances such as ranges, clothes dryers, or furnaces is 240v. Voltages such as 110v, 115v, or 125v are versions of 120v in electrical jargon and voltages such as 220v or 230v are versions of 240v.

It really depends on the size, age, type, brand, etc. But typically, year 2009 refrigerators use between 450-600 kWh/year (and some go well over 700 kWh/year). Larger fridges tend to use more electricity, but some brands are better than others. Try to get an EnergyStar appliance and you should be able get a large 28 cubic fridge that uses around 550 kWh/year which should equal under $60 a year to operate (depending on your electricity costs), which isn't too bad. There are also compact mini fridges and extra large built-ins that could vary in electricity, so it's best to just look up the fridge you are interested in knowing about and check out their website (or the Specs on a store's website). That should tell you how much electricity it uses.
A normal fridge weighs 25 kilos.
if i have 120v and 3hp i need know watts

A lot of them vary, the most common ones will have a volume of 4-5 cubic feet, though you can get them much smaller and larger. That's close to 20 inches in each direction.
Every time you open your fridge door - or indeed your freezer's door - it allows cold air to fall out onto the floor of the room. If this is allowed to happen for more than a few moments the thermostat inside the fridge or freezer, sensing that too much cold air has gone, will turn on the fridge's motor and compressor pump to cool down the new air. The more the compressor pump and its motor are forced to run unnecessarily, the more electricity would be used, with the consequence that the money to pay for that electricity would simply be wasted. Knowing those "facts of life" it should be easy to understand why it is better to keep the door closed as much as possible instead of leaving it to hang open for more than the short time it takes to load or unload food from the fridge.
