What is the difference between coil inductor solenoid?
Physicall no difference.But inductor uses ac and solinoid uses dc.
An inductor opposes a change in?
Current.
Why is the resistance of an inductor low?
Because the whole point of an inductor is to store energy and then give it all back, without dissipating any of it.
How do UV light bulbs work?
UV bulbs are usually fluorescent tubes with the normal white phoshor powders removed. Heaters at each end of the tube excite electrons to 'boil' off the wires. A high voltage is applied via an inductor or choke across the tube ends which sets up a flow of electrons through the tube called a plasma. This is the 'electric blue' of a miniature lightning bolt and emits UV light.
What device works by rotating a wire coil within a magnetic field to produce current?
inductor
What type of inductor is installed in a circuit to impede the flow of ac of a frequency?
A: The inductor is called a RF choke
Another name for a laminated iron core inductor?
choke
What does an electrical choke do?
A choke is an inductor. The impedance of an inductor is dependent on the frequency of the current flowing through it. The greater the frequency, the higher the impedance. Therefore an inductor when used as a choke blocks the flow of high frequency current (by presenting a high impedance), while allowing low frequency or direct current to flow through it. Its function is to block ("choke") high frequencies while passing low frequencies.
What is the function of the choke?
A choke is an inductor. An inductor resists a change in current, by presenting a higher impedance to high frequency parts of the spectrum. A choke, then, passes DC, but does not pass high frequency AC, such as noise.
What is choke coil?
A choke coil is an inductor, which is designed to block a particular frequency in an electrical circuit while passing signals of very less frequency or direct current.
When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
How an electrical choke generat high energy?
A choke or inductor does not generate energy by itself but it can generate high voltages. The voltage across an inductor is equal to the inductance in Henrys times the rate of change of current in amps per second. So if an inductor is wired in series with a battery, then when one of the wires is disconnected the current dops quickly generating a high voltage which causes a spark. This principle is used to generate the high voltage for a spark plug in a car engine.
What is the difference between inductor and inductance?
Inductors can be used for a great many purposes. Terms, such as 'choke', 'reactor', etc., describe applications of inductors.
Working of choke in tubelight?
The choke works as an inductor(filter) induced 850V to 1100V in starting,by strarter make and break of the circuit. After glowing the tube light choke work as inductance and provide 110v to circuit, here the function of starter comes. It helps the chocke to brek from the circuit and to 110v from 850V.thankining U "Nikki"
Inductor works in direct current?
Yes, an inductor works with direct current. It is called an electromagnet. Of course, a practical electromagnet has series resistance, otherwise the current in the inductor would increase to the limit of the current/voltage source.
Why does your electronic ballast hum?
Electronic ballast does not hum as much as a choke. Minute hum of electronic ballast is the small inductor and capacitor producing an oscillation for high voltage generation,
Does a transformer draw a lot of current when first connected to a source?
Yes it does as it is an Inductor and an Inductor needs to build up a magnetic field. It is called INRUSH current.
