Electric field exists around any electric charge which is somewhere in space. If to try to give the graphic representation to electric field, it is possible to make it by means of power lines with a certain direction. Electric fields of a positive and negative charge differ from each other in the properties a little. If in the field of any certain charge to place one more charge, that electric field of the first will begin to affect a new charge with F force el. It is not always simple to find existence of such interaction. In most cases for this purpose special devices and devices will be required.
Instruction
1. To define electric field, the hidden conducting or the place of short circuit, use the special electromagnetic sensor. The sensor, as well as the majority of similar devices, on the basis of registration of conduction electric field which at the time of detection is under the standard tension of network works.
2. Use for creation of the device registering electric field, the amplifier, the rectifier, a key cascade and also the multivibrator to which there is a full scheme of increase in power on VT2 and VT3 transistors.
3. Strengthen tension which frequency of 50 Hz, by means of the amplifier with the antenna. Strengthening coefficient on the antenna can exceed three thousand. Adjust sensitivity of your device by means of the variable resistor. The two-half-period detector under the influence of the device will strengthen tension from an exit. Direct the straightened positive tension on directly to base of the transistor of a key cascade. At achievement by tension on the transistor of value from 0.6 to 0.7 open a key on the transistor and connect a chain of the main drive of a maltivibrator to the main drive.
4. Wait until the multivibrator begins to generate frequency fluctuations, different 2500 Hz. All frequency fluctuations created by the multivibrator will move on the amplifier, and you will be able to hear them in the capsule.
5. After the device is assembled, it is possible to start its use. For this purpose connect to a chain a phase of an electrical network 220B. Adjust tension on minimum that was where to adjust the amplifier handle. For normal work surely during a usage time of the device there has to be a contact with a hand of the one who holds this device, that is with yours. Include power supply of the device and direct the antenna aside where it is necessary to find existence of electric field. Instrument readings will show existence of electric field, at its detection.
