You can convert this to watts, of course, by multiplying amperage by the line voltage.
If this is done, care should be taken to use a meter having a range sufficient to measure the line voltage.
Electrical energy may be transmitted around the world if the line voltage is unlimited.
A leaky cell will be indicated by a reading on the meter equal to the line voltage.
This construction of switches gives ample insulation for the line voltage of 30,000 in this system.
It may be noted at once that in general the line voltage is increased with the length of the transmission.
The vital requirement is that the motors must be in series with each other so that the line voltage divides between them.
This plan is especially desirable when the armatures of several dynamos are connected in series to obtain the line voltage.
