Jul 23, 2015 · So, @William White, according to you, for varying direct current, the current can't be negative basically, but can be in alternating current? And to answer your question, it would be DC I …

Dec 2, 2010 · The correct SI notation for Direct Current (DC) is represented as "I" for current and "U" for Voltage Direct Current (VDC). While "DC" and "VDC" are widely accepted in everyday language, the …

Jun 14, 2006 · Can someone explain breifly or in detail :biggrin: the differnece between ac and dc. Maybe advantages and disadvantages. From what i have researched i know that ac the current flows …

Apr 19, 2006 · An alternating electric current can generate a radiowave of the same frequency, and vice versa: a radiowave hitting a conductor can generate an alternating current in the conductor.
