name the charged particles responsible for current condition in :
a) copper wire
b) lemon juice
c) vinegar

The charge particles involved in the conducting process are:

(a) Copper wire: Copper has some free electrons in its structure and these electrons conduct electricity.

(b) Lemon juice: In lemon juice there is citric acid that gives H⁺ ions which conduct electricity.

(c) Vinegar: In vinegar there is acetic acid that gives H⁺ ions which conduct electricity.
