An electric current in a conductor varies with time according to the expression 1(t) 120 cos(120 m t), where is in amperes and t is in seconds. What is the total charge passing a given point in the conductor from t = 1 s? s to 120 240 a) 0.32 C b) 5.56 x 10-3 C c) 11.1 x 10³ c d) 0.64 C e) 0 An electric current in a conductor varies with time according to the expression 1(t) 120 cos(120 m t), where is in amperes and t is in seconds.
