Explanation:

In electronics, AC is a well - known abbreviation for alternating current. Alternating current is an electric current that periodically reverses direction. Option A (additional charge) is not a standard electrical term related to AC. Option B (alternating coil) is not the correct meaning. Option D (ampere current) is incorrect as ampere is the unit of current, not part of the AC abbreviation. Option E (ampere charge) is also not relevant. So, the correct answer is C.
