JAMB - Physics (1990 - No. 29)
Which of the following statements are true of an insulated charged body carrying positive charge? i. it contains excess positive charges. ii. it creates an electric field. iii. it possesses potential energy. iv. it carries electric current.
i and iv only
i and ii only
i, ii, iii only
i, ii, iii and iv
Penjelasan
The correct answer is C. i, ii, iii only, as the insulated charged body carries excess positive charges, creates an electric field, and possesses potential energy, but does not carry electric current(An insulated charged body carrying a positive charge does not carry electric current because it is not part of a circuit that allows the flow of charge.)
