k will do. how do i test to make sure the transistor is working correctly with a meter? don't forget i'm a newbie but a very fast learner.

The Joule Thief circuit does not have a capacitor.whiz115 said:what? it doesn't oscillate without capacitor?![]()
audioguru said:The base gets noise current which makes the transistor conduct a little.
Of course the 1k resistor supplies some base current to the transistor and turns it on since it connects to the positive supply.eblc1388 said:Audioguru, instead of noise current, isn't the 1K base resistor sufficient to bias the transistor to conduct somehow?

Krumlink said:How it works, is that the transistor makes the coil oscillate, which makes on the other wire a more increased Electromagnetic pickup, induced by electromagnetic waves, called Eddy Currents. Just look up how a transformer works.
