In the UK the mains voltage is 240 volts
The mains voltage is 230 volts, and the frequency is 50Hz.
It depends what country you're in. Here in the UK, the mains voltage is 230 volts.
This question cannot be answered without knowing the voltage. Watts=Volts x Amps In the United States mains voltage (what you get in your house) is 120 Volts, so 120 x 400 = 48,000 Watts In Europe mains voltage is 230 Volts, so 230 x 400 = 92,000 Watts
Not without a suitable mains adapter to charge the battery. The UK mains voltage is 230 Volts - the US mains runs at just 110 colts.
To answer this question a voltage is needed. Amps = Watts/Volts.
Since 1998, the standard mains supply throughout Indonesia is 230 volts, 50 Hz.
Depends. Those intended to run on mains voltage - no. Europe use 240 volts and US 120 volts or so. But as long as you're able to match the voltage, as for 12 volts diode or halogen lights, you're OK.
Depends on where you live in the world. North America it is 120/240 volts. In new installations these days a 200 amp capacity panel is quite common.
The standard nominal mains supply everywhere in the USA is 120 volts AC, 60 Hz.
the voltage of the mains electricity in the UK
in Australia most homes are single phase 240 volts but when measured with a multi meter sometimes you get readings of between 230 and 250 volts
If you mean a Fluorescent tube light then no, you don't need DC. Household Fluorescent light tubes use AC mains electricity. The mains AC is passed through a ballast coil which reduces the current. A ballast coil works best when the AC mains voltage is at least 2 times the Fluorescent tubes working voltage. So, a simple inductor ballast can be used in Europe, where the line voltage is typically 220 to 240 Volts AC, to operate a 4 foot long tube, which operates at 85 to 100 volts, depending upon design. In the US and other places that use 120 Volts AC mains, the ballast is a combination auto transformer (to raise the voltage) and an inductor (the current limiter).
