Using UV-C Light Chambers for Disinfecting Humans from Coronavirus
A rather easy way of disinfecting humans and objects on a large scale and in public places could be by irradiating them with ultraviolet rays (UV-C), in special UV-C illuminated chambers or passages. This includes the pandemic COVID-19, which can be suppressed by installing and implementing these specially created UV-C germicidal lamps. The following article […]
Parallel Battery Charger Circuits Explained
In this post I have explained two methods of connecting batteries in parallel. The first one below deals with changeover circuit using SPDT switches to charge multiple batteries individually or collectively. These may be connected in parallel using a single battery charger and through a manual SPDT changeover switch bank. The seconds design talks about […]
