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
What is LED Forward Voltage?
The forward voltage of an LED is the voltage that must be applied across the leads of an LED, anode to cathode, in order for the LED to function and turn on.
What happens if someone touches a high voltage wire?
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.
What happens if very high voltage is applied to the gate of the n and p channel MOSFET?
punchthru, resulting in destruction of the FET
What does inductive load effect on High Voltage transmission line?
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.
What happens to the diode if it has high piv?
It can be connected in high reverse bias voltage .
Will a LED shine brighter if it is connected to a higher voltage?
A LED has a forward voltage drop dependent on it's composition. It is fairly constant within a small range of current flow. If the voltage is too high and the current is not limited, the LED will burn out. The brightness can be varied by varying the available current, but the voltage across the LED remains virtually the same.
What happens when led is connected in series with capacitor?
As the capacitor charges the led will dim until it's minimum operational voltage is reached and it goes out.
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.

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 the voltage standing wave ratio is too high?
If the vswr (Voltage Standing Wave Ration) is high than call drop chance increase.
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
What voltage does an led bulb need?
Minimum 2V. Some can run as high please check sheerled.co.uk/
Why does a Led have a 470 resistor connected to the LED?
A: That resistor is there to limit the current to the LED it can be any value if the voltage is decreased or increased or no resistor if the voltage across the led is equal to the forward voltage drop.
Give the operating voltage of LED?
A; a LED can have a voltage of 1.8v to 5 or higher voltage whites and red are usually in the low voltage while green and blue are int he range of higher voltage
