As with most small appliances, the wattage used will be on the equipments nameplate. Along with this information you will also find the operating voltage and the equipments operating frequency.

you need to start at your local town hall.

Yes.

The only possible changes would be to the speed of the motors and time keeping.

Depending on the make and construction results may vary. Most modern machines use electronics to control motors and timing, so should be OK.

A switch is a make - break device. Its function is a circuit is to make and break the current flow of the circuit that it is in. This action then starts and stops the load that is connected in the circuit.

Using an undersized power supply is not a good idea. The device drawing 850 mA being connected to a 800 mA source will work but the adapter will get warm to hot over a period of time. This overloading of the power supply will eventually destroy the adapter.

Yes, the manufacturer specifies what the working voltage of a device will be and that voltage has to be adhered to.

No.

No, 12 volt AC is a different from 12 volt DC. Have a second look at the 12 AC volt adapter's output label. Most adapters contain a bridge rectifier in them that makes a conversion within the adapter. An example of this is in phone chargers.

Answer for USA, Canada and countries running a 60 Hz power supply service. Watts= voltage X amps At 120 volt total watts would be 2400 at 20 amps. The electrical code states that circuit conductors that are fed by this breaker on a continuous load can only be loaded to 80%. #12 wire rated at 20 amps, derated to 16 amps continuous = 16 x 120 = 1920 watts, #10 wire rated at 30 amps derated to 24 amps continuous = 24 x 120 = 2880 watts. On load calculations this derate should be taken into consideration. To maintain the required wattage needed for the load the wire size and/or the next size breaker may be needed.

The only way to do that is with a transformer. They make inline transformers that convert 230 to 115 and they simply plug in inline.

It is not recommended to do this. The reason being is that if both appliances are on at the same time, there is a chance that the breaker will trip. If the breaker is not reset right away it will leave the refrigerator with no power. A fridge with no power will start to defrost if it has a freezer compartment. When new homes are being built electricians wire each individual appliance outlet as a dedicated circuit, meaning that only one appliance outlet is assigned to that circuit and nothing else.

yes, it will just charge the device faster..

Anyway, the 800mAh batteries will last longer than the 600mAh ones because they have more storage capacity.

See: http://www.greenbatteries.com/nibafa.html#mAh%20defined

Anyway, you can get even better batteries (up to 1000mAh) here: http://www.thomas-distributing.com/aaa-nimh-batteries.php

You will notice a big difference in play time between 600 and 1000. The bigger the better.

since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.

No, the excessive voltage will destroy the equipment, unless the fuse trips (hopefully) ...

American electrical plugs have three prongs in the shape of a triangle but two of the prongs are thin lines while the third one is kind of like a cylinder, but some don't have the cylinder just the two lines.

Yes - what matters is the voltage - it has to be the same. The device will only draws 1A as needed - the adaptor with higher amp,i.e, 2A is fine. As long as the adaptor has amps equal to or greater than

those of the device, it will be ok!

You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance

I believe it would be best for you to ask your local Electric Company..considering that different areas may have different hours? Hope tis helps..:)

Normally in the US voltage for TVs is 120 volts at 60 Hz (hertz). Many countries use 220, 230 or 240 volts at 50 Hz. To understand hertz, you need to understand AC voltage. AC voltage cycles between a positive voltage and a negative voltage. It basically goes up to the peak voltage, then comes down to a negative voltage. It does not do this instantaneously, but instead, does it over time. If you were to graph this pattern, it would form a sin wave, which would slope up, then slope back down. It looks like the tilde on a keyboard "~". Each time this full cycle happens within 1 second, we call it a hertz. So our 60 Hz system would cycle from positive to negative 60 times a second. When you see Hz, it means cycles per second.

I am not a TV expert, but I think some manufacturers double the cycles per second to 120 Hz so that they can refresh the picture twice as fast in order to try to get rid of flicker and show a cleaner looking picture.
