Tiêu đề Current Electricity (T.ro Fl.Q.) E.pdf ✅

PHYSICS Q.1 A steady current passes through a cylindrical conductor. There is an electric field inside the conductor. Ans. [True] Q.2 The path of free electron in a metal is curved between successive collision in the presence of external electric field. Ans. [True] Q.3 In an electrolytic solution the electric current is mainly due to movement of free electrons. Ans. [False] Q.4 When potential difference is applied across the ends of a conductor, then the free electrons of conductor are accelerated and their velocity gradually increases. So the current in conductor increases from one end to other end. Ans. [False] Q.5 An ammeter with internal resistance 90  reads 1.85 A when connected in a circuit containing a battery and two resistors 700 and 410  in series. The actual current will be 1.85 A. Ans. [True]
