3 days ago · Instead of a single pair of wires for current and voltage, Kelvin split the arrangement into a force pair for current and a sense pair for voltage. (Image: Maxim/Analog Devices). The current to be measured goes from the battery through the ammeter (A), and there is a voltage drop across the resistor between leads 2 and 3.
3 days ago · I have a radio that took a surge. It blew the component off of the board but no board damage. I would like to identify what this component is so I can replace it. The component is on the + DC voltage side right after the fuse. I tested a good radio and it tests similar to a diode but I cannot find a similar part from pictures. Can anyone identify what this is? It is the small white chip which ...
3 days ago · Photovoltaic effect. The photovoltaic effect is the generation of voltage and electric current in a material upon exposure to light. It is a physical phenomenon. [1] The photovoltaic effect is closely related to the photoelectric effect. For both phenomena, light is absorbed, causing excitation of an electron or other charge carrier to a higher ...
3 days ago · Baluns made with autotransformer windings are also called voltage baluns, since they produce balanced output voltage, but not necessarily balanced current. Picture a balun of the same design, wound on ferrite toroid.
4 days ago · Objective Using pediatric anthropomorphic phantoms (APs), we aimed to determine the scanning tube voltage/current combinations that could achieve optimal image quality and avoid excessive radiation exposure in pediatric patients. Materials and methods A 64-slice scanner was used to scan a standard test phantom to determine the volume CT dose indices (CTDIvol), and three pediatric ...
1 day ago · Ritz Instrument Transformers, Inc. has announced plans to construct a new manufacturing facility in Waynesboro, Georgia focused on high-voltage instrument transformers. The investment is projected at $28 million, set to generate 130 jobs in both manufacturing and professional capacities. Construction is slated to commence in October 2024.
