It can be connected in high reverse bias voltage .
when a LED is subjected to a high voltage it will heat up and burn the internal junction, which will leave the LED open circuit.
In this case current flows from a high voltage to a lower voltage in a circuit.
depending at the kind and high at the voltage, or/and the high of the power
Spark plugs don't produce high voltage they just make sparks with high voltage. The high voltage in a car is produced by running the low voltage of a car through a coil and condenser a distributor defines exactly when the spark happens to light up the fuel in the cylinder
If the vswr (Voltage Standing Wave Ration) is high than call drop chance increase.
high voltage pass 220v instead of 110 to xerox 7335 machine
cureent becomes high
If they are grounded they get an electric shock or electrocuted. If they are not grounded or in simultaneous contact with the neutral wire, nothing. That's why birds can sit on a high voltage wire and survive; they are not grounded.
Yes ... sort of. Without a conductor the voltage must be high enough to jump the gap. With lightning this happens all the time (the voltage is massive), but seldom happens with commercial power supplies.
Usually high voltage is considered anything over 1,000 volts. However, in 1897 the Niagara Falls Project used rubber insulated cables for 11,000 volt circuits.
The abbreviation, 'PT', stands for 'potential transformer' (in Britain, the abbreviation is 'VT', and stands for 'voltage transformer'). This, together with a 'current transformer', falls into a category of transformer known as 'instrument transformers'. A 'PT' or 'VT' is used to reduce a high voltage to a level of voltage that can be safely read, remotely, by regular a.c. voltmeters or to provide inputs to high-voltage protection relays, while electrically- isolating the secondary circuit from the high-voltage primary circuit for the purpose of safety.
