Usually 110 volts
The fuse is what restricts how much current you can draw from an outlet. If you have the wrong fuse you can draw more power than intended from an outlet - but only if the appliance plugged in can use it up. To get too much power out of an outlet, with a suitable appliance plugged in, then you also have to have a higher voltage in the outlet. And for that to happen, something has to be seriously wrong higher upp in the supply chain.
when in good working condition an automotive battery should supply between 12.6 and 13.8 volts
read the manufacturer's nameplate on the unit.
30%-60% is usually the discount for men's shoes at outlet stores.

There is no loss in voltage. Voltage is constant (dependant on your supply). The dimming is as a result of of a reduction in current (ampage)
The current depends on the supply voltage.
It will work fine as long as the supply voltage matches the device. They both must be 12V, and both usually must be the same type-- either AC or DC. The supply current must be at least as much as the device requires.
230v power supply .................it requires 12watts......
First of all, let's get the terminology correct -there is no such thing as a 'voltage difference'. 'Voltage' is another word for 'potential difference', so 'voltage difference' would mean 'potential difference difference', which doesn't make any sense! So you should be referring to the voltage across the holes of an outlet, not the 'voltage difference' across those holes.The voltage produced by a generator in the power station produces a much greater voltage (up to 30 000 volts) than the voltage that appears across your outlet (120 V in North America or 230 V in Europe). Furthermore the generator's voltage gets increased even higher (hundreds of thousands of volts) before the electricity transmission can take place. Eventually, those high voltages are reduced, using transformers, until it reaches your outlet.
By using a voltage divider, that is two resistors of the same value in series across the DC supply. Half of the supply voltage will be at the point where the two resistors is connected. But how much wattage of those resistors is also an issue.
