For the detection of concealed electric finding a wire break in the wiring or cables, identify the bulb in Electrogarlands in most cases it is a fairly simple device, consisting of a field effect transistor, the headset and one to three batteries (Figure 1). The operating principle of the device is based on the ability of the channel FET change their resistance under the influence of interference on the gate terminal. Transistor VT1-KP103, KP303 with any letter index (the latter is connected to the output of the housing gate terminal). Phone BF1 - high resistance, the resistance in 1600 ... 2200 ohms. Polarity battery GB1 is not important.
