Transistors: Output Characteristic Curves

jc2048

This one is similar to what I did with the gain, except that this time I kept the base current constant and measured the collector current in relation to the collector-emitter voltage. I reworked the original test circuit, which is how this blog foll...

How one electrical passive element can cause issue

kk99

Few days ago I got TV with following issue: there is no way to power on TV (only standby LED is on). I have checked that all voltages on IP board (power supply and inverter) were correct. Next I have checked key elements on main board. After analyze ...

Transistors: Current Gain (Beta or hFE)

jc2048

Another 'Transistors' blog. I thought this one would be easy, but it turned out to be quite challenging and, in some ways, a bit of a failure. The current gain of a bipolar junction transistor (when the emitter is the common terminal bet...
