how is an electric circuit shielded from stray electric field by placing It inside conductive box.?????????
Answers
Use a conductive box which completely surrounds the equipment, so shielding it. Any stray electric fields will cause charges on the surface of the box to re-distribute (since it conducts), and so cancel any strong fields inside the volume it encloses. No electric field can then penetrate the box to disrupt the circuit inside it.
