Hello guys , In this post we learn how to make ac detector circuit in easy way.
Let start it:-
*Specifications
-check ac current wireless follow or not.
-check ac current without touching follow or not.
- safe in use and cheap in price.
*Parts list
1.Bc547 / Bc548 / 2N3904
2.Led ( 5mm 3v)
3.copper wire
*Schematics and diagram
- connect all the transition and components according to this diagram.
-make Cooper wire coil and add in the first transistor base.
- if you have not bc547 transtior use this alternative transistor like Bc548 or 2N3904.
*How to use
-put copper wire coil near the ac current wire.
-when light on the circuit are glow that indicate ac current flow on this wire. then not glow the ac current not follow in circuit.
