The electrician who installed the fluorescent light fixture in which this ballast was used wanted to make a very reliable connection between the ballast wire ends and the electrical circuit - or perhaps the factory sold the ballast with its wire ends also solder-coated. In my photo below you c...

In my photo above you can see that this fluorescent light fixture, an original fixture installed in the bathroom of a Two Harbors MN home built in 1963, used two straight bulbs as there are two base connectors at each end of the fixture. I have also marked the starter found at one end...
Molecular medicine Fluorescent In Situ Hybridization. A method for locating a segment of DNA on a chromosome. The DNA is labeled with a fluorescent dye and hybridized to a cytological preparation of chromosomes that has been denatured to allow nucleic acid hybridization between chromosomal DNA and ...
The fins in this group consist of a web of skin supported by horny rays. Each ray is moved by a set of muscles, giving the fin great flexibility. Most ray-finned fish have overlapping scales made of very thin layers of bone. Their skeletal structure is light but strong and most have ...

The capacitor in a fluorescent lamp is primarily used to improve the power factor of the lamp's circuit. It helps to correct the phase difference between the voltage and current in the circuit, which can improve the overall efficiency of the lamp. Additionally, the capacitor helps to stabilize...
This is called a Premises Connection Device (PCD) and it is where the internal Optical Fibre cabling joins the Fibre cabling from the street. An Optical fibre cable is run from the PCD to the Network Termination Device (NTD) inside the house and it is where the optical signal (light) is...
Voltage spikes or surges are typically caused by switching heavy loads (drawn by all manner of industrial machinery, lift motors, welders, fluorescent lights, fridges, and so on) on or off. At a point in its sinusoidal cycle when the mains power‑supply voltage nears its peak (a nominal ...
