Electro meter by FET 2N3819


Electro meter by fet 2n3819

Today we try to come to see the circuit checks the static electricity is simple. OR Electro meter by FET 2N3819. It can show the electricity bill dwells to follow the inventory that has the electric charge. Such as the plastic is , hand , etc. By detect far get 30 centimeter. Fine the value R1 give the meter can read the value 1mA. When lead load come to near an antenna very a little ? The value will that can read to is down in proportion. Request a friend has fun Electro meter Circuit this please sir.
