Most of Europe uses a 230V system.
The voltage is 230volts and this is the norm in Europe.
The standard household AC electrical power mains voltage in Greece is 230 volts, with a frequency of 50 Hz.
I have a sole F60 bought in US and I use it now in France with a transformer ; you never know if you can use it or not, sometimes it works , sometimes not...I don't know why maybe it's a problem of frequency...
No, it is not safe to use a higher voltage power supply (12V) for a device that requires a lower voltage (7.5V). This can damage the device and potentially cause a safety hazard. It is recommended to use a power supply that matches the required voltage (7.5V) and current (1A) specifications of the device.
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
Yes, it can. The only one thing you need to take care of is power. In Europe people use different standards for the power line (different voltage). So if you want to use the router in Europe you have to get an appropriate power adapter.

Transformers do not exactly transfer power, they either step up voltage or step down the voltage from one source to another to make it a useable voltage.
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
A power substation is used to reduce the voltage from high voltage power lines to a voltage that is less dangerous that you can use in a house for example. It is less costly to transmit electrical energy over long distances using high voltage.
Do you have a choice ? All my power tools are 110 volt, so that is what I use.
Power = voltage x current Number of power in volts

The voltage your computer's power supply receives depends mainly on the standard electrical service delivered into homes, offices and factories by the national electrical grid in your country.Just a few examples: if you live in North America, that voltage is 120 volts but, if you live in, say, Europe or Australia, that voltage is 230 volts.More detailsThe voltages a power supply was designed to use depends on how old it is. Early power supplies were designed to use only one voltage: the standard voltage of the electrical service delivered by a country's national electrical grid for use by small appliances in homes, offices and factories .Since the invention of the personal computer most standard power supplies have been designed to operate on a wide range of voltages. (Such as from 100 volts to 250 volts.)
