Yes in most cases. If you live in the US and your appliance was made to work in the US and you have Two Hot conductors, red and black and your appliance says its rated for 220 V your ready to roll. If you live in the US and your appliance was made to work elsewhere in the world with the exception for Canada then its very doubtful. The US uses Split-Phase 240V so you can get 120V Circuits also and most of the rest of the world uses 240V Single Phase right to their regular receptacles. 220V is an archaic term and is meant to be used in the 220V-250V range
Yes. Generally 240V is actually 220V when it reaches a wall socket in any case: (DO NOT TRY AND RUN 110V EQUIPMENT ON 240V SUPPLY THOUGH)
(from http://www.faqs.org/faqs/electrical-wiring/part1/section-14.html)
Yes, 220 and 240 volts are a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of 1% on the load current. eg. Wattage load of 2400. Amps = watts/volts. 2400/240V = 10 amps. 2400/220V = 10.9 amps. On a constant resistance as the voltage goes lower, the current goes higher and vise versa as the voltage goes higher, the current goes lower.
Yes they would, because the last 20 years manufacturers have build in a 15% tolerance in their electrical appliances.
on some appliances you can, but it is not recommended
Yes, a 240 volt appliance will work with a 200 volt supply.
Yes
normally, appliance are built in 110v or 220v, applied in 100-140v and 200-240v. if your 250v appliance is common home appliance equipment, then 220volt is ok, i think. otherwise, you should ask the vendor for special power supply.
No, this should not be done. If the appliance is a heater it will operate over its given specified wattage. A 200 volt heater run off of 240 volt will have an output increase. Ohms law stated that current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. A 240 volt heater can be run off of a 200 volt supply but the wattage will be reduced. For example if the heater is 5000 watts at 200 volts, the current is I =W/E 5000/200 = 25 amps. The resistance of the heater is R = W/I (squared) =5000/25 x 25 (625) = 8 ohms. Applying 240 volts on the same heater whose resistance is 8 ohms results in this new heater wattage rating. W = E (squared)/R = 240 x 240 (57600)/8 = 7200 watts. This is 2200 watts higher than the manufacturer's safety rating. W = watts, I = amperage, R= resistance in ohms and E = voltage.

In principle you can but in practice it is not done. A 220 v supply might have to provide (let's say) 200 watts of power for a TV. That would mean that the current drawn at 1.5 volts would have to be at least 140 amps, and that kind of power is not normally available.
No. If you connect two 12 volt batteries in series(positive to negative) to make 24 volts, you will have 100 amp hours. If you connect two 12 volt batteries in parallel(pos to pos, neg to neg) you will stay at 12 volts but have 200 amp hours

It will work but not as efficient as the manufacturer designed it to. If motors are involved in the appliance they will run hotter as they will draw a higher amperage due to the lower voltage. Appliances with a wattage rating for heating elements will not reach their nameplate wattage rating.

If a precision voltage is needed from 200 to 230 an auto transformer could be used. If the load is a 230 volt motor to be operated on 200 then add 15% to the nameplate full load amperage for the calculation for overload protection.
The depends on the current drawn by the 240 Volt battery charger. Some appliances, such as small battery chargers, small "voltage converters" for international travel, electric shavers, etc., have been designed to run safely on different supply voltages. The appliance's label or "rating plate" will state the range of voltages it can safely be used on. Whilst a small appliance like that will work fine as long as it was made to handle the lower voltage, it's not possible to use a small "voltage converter" for international travel with high-powered appliances such as 220 - 240 Volt electric kettles. The reason is because the current they draw is much too high. Larger 220 - 240 Volt appliances having powers from (say) 100 - 200 Watts (which may be the case for a large battery charger) to 2000 Watts (2kW) or more, like an electric kettle, would need an expensive item called a "Transformer" or "Auto-transformer" to enable them to be used on a 120 Volt supply. Such transformers are much bigger - and heavier - than the small "voltage converters" that are available for international travel. Large transformers are also much more expensive: they can cost from US$100 upwards, even second-hand, depending on the power to be converted. So most folks would just buy a 120 Volt appliance locally in the 120 Volt area. After all, a cheap electric kettle can cost less than US$20 and a really fancy one can be bought for under US$100.
Kenmore appliance parts can be found at the website sears parts direct, the website has about 200 parts for every model of appliance made by Kenmore you could possibly want.
As Dave says there is no obvious reason to do so. However if you put a 200mA fuse or circuit breaker in series between the supply and the load you will protect the load from pulling more than 200mA from the supply should the load malfunction. That way the load is protected from damaging itself (if that was your concern).
Probably about 180 watts, assuming 90% efficiency.
Everything would work as designed if you used a 2 amp power supply for a 200 ma circuit.It's important to not go OVER the designed capacity of the power supply, and in fact, it's a good idea to make sure the power supply has at least double the capacity of the load current.
