Simple transistor circuit for beginners

If you are a beginner in electronics then some of you must have certain confusions in understanding circuits, like the symbols, joints, components values etc.

So an easy way to become a master in understanding circuit's, start by doing certain simple circuits like this.

For better learning try to make circuits that you are really interested in.

Not all those circuits available in Google.

Here below is a simple led blinker circuit using a single NPN transistor.

This circuit run's at 12 volt dc.

You can experiment this circuit using any NPN transistor and also by changing the value of the capacitor.

Capacitor value determines the duration or speed of the led blinking interval.
