Yes and No. Like a battery, no. If it is an electronic one probably only for a millisecond. If it is a magnetic ballast it can store a small static inductive charge of electricity. A ballast basically a step up transformer with two coils of wire in it. When you shut off the switch the low voltage supply side coil the electrical field collapses and drains immediately but the high voltage side coil connected to the light also collapses but at a slower rate because it is isolated from the low side and has to "leak" back to the low side or through the metal case to ground. It can take a few seconds or so for it to drain completely. Shut off the light and give it a minute before you do anything.

What does static electricity and current electricity have in common?
They both cause by electrical charge
Has electricity always existed?
yes, electrical pulses control your muscles. hence if you you get an electrical shock your muscles tense up.
How does lighting affect electricity?
cause lightning is electrical.
Where is the store of electrical energy in a circuit?
Capacitors, inductors, and batteries all store electrical energy.
Do all circuits contain electricity?
All electrical circuits do.
How do you change a ballast?
There are many types of ballasts in the electrical industry. To get an answe, the type of ballast must be stated.
Can an electrical timer be used to control on and off power to self ballast lamps?
Yes, an electrical timer can be used to control the on and off operation of the power to self ballast lamps.
Can you put electricity in a jar?
No, electricity cannot be put in a jar. Electricity is the flow of electric charge through a conductor, and it requires a complete circuit to flow. You can store electrical energy in a battery or capacitor, but you cannot store the flow of electricity itself in a jar.
What can store electrical energy in circuits?
There is no easy way to store electricity. capacitors can store a charge but for commercial usage totally unsound. The way that man learnt o store electricity is by building dams and storing water. So when watter is released energy that energy can be converted to electricity.
What is ballast resistance?
A ballast resistor is an electrical device inserted into a circuit to compensate for changes arising from temperature fluctuations. It helps regulate voltage flowing in an electrical system to avoid overloads or battery damage.
What is a ballast resistor?
A ballast resistor is an electrical resistor whose resistance varies with the current passing through it, thus maintaining a constant current.
What the difference between ballast and transformer?
A transformer changes the amperage and / or voltage. It literally "Transforms" electrical energy. A ballast is like a capacitor. Think of a ballast as a short-term battery. It stores power then releases it as needed. A common example of a ballast is on fluorescent lights. Initially, a fluorescent light needs a big blast of energy to excite the gas molecules into emitting photons (light). Then it only needs a small amount of energy to keep the gas molecules in an excited state. However, that power has to be of consistent amperage and voltage. The ballast is designed to do that. The electrical ballast stores energy in the same way that a water ballast stores water for stability. Because the electrical ballast stores far more power than the device it regulates requires, it too provides a kind of electrical stability. That's why you often see a fluorescent light flicker or "lose stability" when the ballast starts to go bad. A transformer transforms voltage and amperage up or down. A ballast provides a stabile power supply.
How much electricity does a T8 32w fluorescent light bulbs use?
These tubes need a ballast to operate the tubes. The current and voltage will be marked on the fixtures ballast.
What are the three examples of electrical energy?
three types of electrical energy is an outlet, a lightbulb, and the sun. I know these are right because my teacher told me.
Why do ballast get burned?
Heat is generated in a working ballast because of the current flowing through it. Heat is bad for any electrical/electronic device and will eventually cause it to fail.
How do you determine the correct replacement ballast for 120 volt T12 dual tube fixture?
There should be a label on the old ballast. If so take down all the information for amperage and voltage. You should then be albe to get a replacement at any Lowes, Menards, home depot, any other home improvent or electrical supply store.
Which electrical wires bring electricity to an electrical device or motor?
which electrical wires bring electricity to an electrical device or motor The cable, otherwise known as the flex or the lead.
