From a three phase four wire distribution system the voltages would be as follows. From L1 to N - 277 volts. From L2 to N - 277 volts. From L3 to N - 277 volts. From L1 to L2 - 480 volts. From L2 to L3 - 480 volts. From L3 to L1 -480 volts.
12 volt
All voltage reading are usually read with a volt meter. This volt meter can be a hand held unit like electricians use.
No a 208 volt outlet does not need a neutral. 208 volts is the line voltage between any two legs of a three phase 208 volt system.
Nine tenths of the voltage would appear across the 200-ohm coil.
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
Originally it would have been a 6 volt system.
Hook a 12 volt light to a 24 volt system and the light will burn out in seconds. You need a step-down voltage converter to do this.
If you have 123 volt at the plug, this means that the voltage is a little high, or that the reading could have been taken at night when the system load was low. It is still safe to connect your appliances to it.
The 1964 VW Beetle came from the factory with a 6 volt electrical system. Unless it has been upgraded to a 12 volt system you would need a 6 volt battery. I would recommend you check the voltage of the current battery with a volt meter. If there is no battery in the vehicle, just remove a light bulb and check the voltage written on the bulb.
In the US the voltage is about 220 volts. This voltage is based upon the average voltage of the AC sine wave. It can peak as high as 240 volts or as low as 210 volts. So these different voltages are actually referring to an average 220 volt system.
12 volt
It is a 12 volt system.
Depending upon the voltmeter, the 300 volt range would typically be the most correct to give you a mid-scale reading of 120volts.
No, it would glow very dimly or not at all. Bulbs must run at the voltage they were designed for.
There are three main categories of low voltage. It depends on what type of system the voltage belongs to, as each system has a bottom end or low voltage assigned to it.
From the factory it will have a 6 volt, positive ground system. However, it is popular to replace the original system with a modern 12v system.
With engine running, ensure system voltage is in the 13-14 volt range.
