Can an alternating static charge at one end of an iso lated conductor, developed by an alternating current, be detected by a gold-leaf electroscope? |

Answer» Solution :Yes, a gold-leaf electroscope can detect alternating STATIC charges. The divergence of the gold leaves in this electroscope DEPENDS only on the magnitude of charge in a test body, not on the nature of charge, i.e., not on whether the charge is positive or negative. The average of this magnitude of charge, over a complete period of the alternating source, has a finite value-this average is never zero. So, when the test body is brought NEAR the disc of a gold-leaf electroscope, this average non-zero value of charge will be the input on the electroscope. The leaves will diverge ACCORDINGLY. |
