If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What is volage ratio of potential transformer?
The voltage ratio of a potential, or voltage, transformer (PT or VT) depends upon the primary voltage to which it is connected. Accordingly, its voltage ratio varies considerably, as there is huge variety of system voltages throughout the world.Typically a VT's secondary voltage is standardised at 110 V which will match the full-scale deflection of a voltmeter connected to it (although it can also supply protective relays), while its primary voltage is then matched to the voltage of the system to which it is connected: in the UK, for example:11-kV:110 V33-kV:110 Vetc.
Which configuration of bipolar junction transistor which will give both current gain and voltage gain?
high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode high current gain :-common collector since it is the ratio of Ie/Ib
What is medium and high voltage?
Medium voltage is over 1000 v, high voltage is over 45 kV.
When was High Voltage Festival created?
High Voltage Festival was created in 2010.
Why doesnt a bird standing on a high voltage wire get electrocuted?
The wires are coated in rubber.
What happens to the diode if it has high piv?
It can be connected in high reverse bias voltage .
How do you find primary number of turns in a transformer?
Unfortunately, it is not practical to find the number of turns in a transformer's windings. However, what matters is its turns ratio. This can be done by applying a low AC voltage to the higher-voltage* winding, and measuring the resulting voltage appearing across the lower-voltage winding. The turns ratio will be approximately the same as the voltage ratio.(*NOT THE OTHER WAY AROUND! Or you may up with a dangerously-high voltage induced into the higher-voltage winding!)
What happens to an LED When the voltage is to high?
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.
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What happens when a bulb of 6volts used in an circuit?
depending at the kind and high at the voltage, or/and the high of the power
How spark plugs produce high voltage?
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
What happens when high voltage pass 220v instead of 110 to xerox 7335 machine?
high voltage pass 220v instead of 110 to xerox 7335 machine
How do you step down voltage in transformers?
step up or stepdown is done by the ratio of the number of turns in the primary / secondary coil, large number on high voltage side small number on low voltage side. the wire used on the low voltage side would be thicker than the high.

What do you mean by tapping of transformer?
'Tappings' are externally-accessible electrical connections to the turns of a transformer's (usually high-voltage) winding. This enables the number of turns to be changed, resulting in a change to the transformer's turns ratio and, therefore, to its voltage ratio. Tap changing enables the electricity network company to adjust the turns ratio in response to any excessive voltage reduction resulting from a heavy load.
Which configuration of bipolar junction transistor which will give both current gain and voltage gain?
high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode high current gain :-common collector since it is the ratio of Ie/Ib
