A Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents. Tesla's original circuits as well as most modern coils use a simple spark gap to excite oscillations in the tuned transformer.
Proton-exchange membrane fuel cells, also known as polymer electrolyte membrane fuel cells, are a type of fuel cell being developed mainly for transport applications, as well as for stationary fuel-cell applications and portable fuel-cell applications. Their distinguishing features include lower temperature/pressure ranges and a special proton-conducting polymer electrolyte membrane. PEMFCs generate electricity and operate on the opposite principle to PEM electrolysis, which consumes electricity
PLM stands for Product Lifecycle Management. PLM allows an organization to control all aspects of a product configuration, not just the design data. From project inception to design to manufacture and even obsolescence, PLM is a tool that ties everything together.PLM is critical for complex products that encompass many different design elements. Letâs take an example of something most of us are carrying right now, a mobile phone.ithout a PDM system it is not easy to ensure that everyone is not overwriting each otherâs data or that everyone is working on the latest versions of files. Speaking of versions, PDM systems make it easy to maintain version and revision control of designs, ensuring your design history is maintained.
