10. The Procedure of the Electric Field Research
1. Put two electrodes in a dish with water.
2. Copy the position of the electrodes in the dish on the certain
coordinate grid on the paper.
3. Connect electrodes to the source of voltage and switch it on.
4. Choose no less than 10 reference points.
5. Set one sensing finger on one of the reference points.
6. Without moving the sensing finger, by another sensing finger
detect the equipotential points when the null detector indicates zero.
7. Copy coordinates of all equipotential points on the coordinate
grid on the paper and draw equipotential lines.
8. Draw perpendicular lines to the equipotential lines.
11. The Tasks of laboratory Work
Research the electric fields of the next system of electric charges
(Fig.11.1).
