As an extension of my previous inquiry into air-core chokes, I'm trying to determine the voltage insulation rating of magnet wire, without much luck. Few of the audio air-core choke manufacturers list ...
I've made a joule thief, and it works fairly well, but not as well as I would like. It's powering a 3.2v LED from a 1.2v battery, but it's very dim. I'm hoping increasing the voltage from the JT ...
I was working on some RLC circuits and I found a question something like this. In series RL circuit, \$V_R\$ = 4V and \$V_L\$ = 3V. what is the magnitude of total voltage ? I just thought \$V_T\$ = ...
I'm trying really hard to understand inductors and their related kick back voltage when the current is suddenly interrupted. Example ascii art: 1 2 | | + ----- ~~~ --_-- - ...
