    (a) How is the direction of electric current related to the direction of flow of electrons in a wire? (b) Calculate the current in a circuit if 500 C of charge passes through it in 10 minutes.                

    Answer:

    (a) The conventional direction of electric current is opposite to the direction of flow of electrons in a wire.                                                                                  (1) (b) Q = 500 C t = 10 min = 10 x 60 = 600 s                                                                                                                                                                                        (2)
