Where is the ballast resistor on a 2000 Chrysler Sebring convertible?
It does not have a ballast resistor.It does not have a ballast resistor.
I've changed the bulbs in a 40 inch fluorescent light fixture but it still goes out. What might be wrong?
It sounds like your ballast is malfunctioning. If it is a magnetic ballast it will probably have tar protruding out of it and the ballast will be very hot. Buy a new electronic ballast. Change the wiring to the end sockets like it is shown on the electronic ballast print that can be found on its label. You will need new tubes for the new ballast. Diameter will be T-8.
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.
How can you find out if your fluorescent lights are using too many amps?
The amperage is printed on the ballast. If your meter reads higher that that what is printed there, then the ballast is drawing more amps that it should.
How do you replace flouresent bulbs?
The long, tubular ones usually rotate and slide out. The curly ones have standard light fittings. Remember to dispose of the old bulb in a designated re-cycling container for them because they contain mercury which will harm people if it gets into the environment (do not break the tubes).
What is the purpose of a submarine's ballast tanks?
to keep the sub level or help it to dive and surface
How does a submarine change its density?
To be able to submerge in the water, the sub has to become heavier. Ballast tanks are utilzed for this purpose. Water is let into them, and the sub sinks. To rise, air is pumped into the ballast tanks, and the sub rises.
What is ballast and trapped fuel?
On occasion, ballast is required to bring the centre of gravity within operational limits. There are two methods of carrying ballast: - Ballast (hold loaded) -Ballast fuel: the fuel used for this purpose is called ballast fuel. Trapped Fuel:The fuel in an engine or fuel system that is not in the fuel tanks
Why do submarines work?
Submarines have ballast tanks in them.........when it has to go deep down, the ballast tanks are filled with water, which increases its average density in regard to water(Relative Density).....and when it has to come up to the surface it empties the ballast tanks...and it rises. That's it.
How many ballast tanks are there in a submarine?
It depends entirely on the size of the boat, but 5 or 6 Main Ballast Tanks (port and starboard) and 4 or 5 Trim Tanks are the average.
What is the purpose of a submarine ballast tasks?
They help the sub go up and down. When water is allowed into the tanks, the sub goes down. When water is pushed out of the tanks, sub comes up.
What is a submarines buoyancy?
A submarine has a variable buoyancy due to it's ballast tanks. When a submarine submerges, it fills it's ballast tanks with water which causes negative buoyancy. When a submarine surfaces, it pumps the water out of the ballast tanks thus giving it positive buoyancy.
What is main ballast of a vessel?
Ballast used to be stones. With the invention of the electric pump, I think most ships will actually pump water into and out of tanks to adjust their ballast now.
Where can you purchase ballast tanks?
Ballast tanks aren't necessarily a specific item - they're designed specifically for the vessel involved, and custom built. Main Ballast Tanks are nothing more than open air spaces between the outer hull and inner hull of a submarine; they're normally full of air on the surface, and a hydraulically actuated valve (which can be manually operated as well if needed) opens to release the air through a vent at the top of the tank, letting water in through open grates in the bottom of the space. Variable Ballast Tanks (Trim Ballast Tanks) are simply water tanks of custom design and manufacture for each individual boat. They're tied to pumps that can rapidly fill or drain each tank as needed for increasing ballast, or leveling the boat. Anything that holds water and can be connected to a pump which can fill and drain it can be used as a ballast tank.
What is a ballast tank?
A ballast tank is one of several external or internal tanks fitted in submarines, which allow the boat to submerge when filled with water.
How do fluids help ballast chambers on a submarine?
A submarine actually controls its weight by allowing water to enter or exit hollow chambers in its hull. These chambers are called ballast tanks. Ballast is anything carried in a ship to give stability. When water is allowed to flood into a submarine's ballast tanks, the weight of the submarine increases. When this increased weight exceeds the submarine's buoyancy, the submarine will sink. To allow the submarine to rise, air is pumped into the ballast tanks. The air forces out the water, reducing the weight of the submarine. The submarine then becomes lighter, buoyancy increases, and it floats to the surface. A submarine can also be made to "float" underwater at any depth by adjusting the amount of water weight in its ballast tanks.
How is the descend and the ascend of a submarine controlled?
By pumping water or air into the ballast tanks.
