A toroid coil in an electronic ballast is used for energy storage and to help regulate the flow of current in the circuit. It also helps to reduce electromagnetic interference and noise. Overall, the toroid coil plays a crucial role in the functioning and efficiency of the electronic ballast.

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 tube light glow without starter?

yes..if we replace magnetic ballast with electronic ballast...there is no need of starter if we use electronic ballast.


What does a magnetic field for a toroid look like?

A magnetic field for a toroid is typically concentrated within the coil, circling around the winding. Inside the toroid, the magnetic field lines are close together and form closed loops. Outside the toroid, the magnetic field is very weak and essentially negligible.

Where is the strongest field in a toroidal magnet?

according to the ampere's law . magnetic field is strongest in a loop or a plane. and about toroid the magnetic is strongest in the coil where the wire is rotated around it . Magnetic field is minimum inside and outside the toroid.


How do you rewire a magnetic ballast F96T12 fixture to work with a new electronic ballast?

The end sockets have to be rewired. The schematic for the rewire is on the ballast label.


Why does magnetic ballast take more power than an electronic ballast?

Because it wastes less energy in the form of heat.


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.


What does an electronic ballast do?

Electronic ballast is designed to limit the current which goes through an electrical circuit. This keeps the circuit from overheating or suffering other ill effects from having too much current.


Where is the ballast resistor located on a 1987 Dodge D150?

near the coil on the manifold


What if your ballast resistor is bypassed on your 1973 350 Chevy engine Why?

Eliminating the ballast resistor will cause excess current through the coil, and will cause excess current through the points.When that happens, the points and/or coil will fail prematurely.
