An electric current in a conductor varies with time according to the expression i(t) = 110 sin (120πt), where i is in amperes and t is in seconds. what is the total charge passing a given point in the conductor from t = 0 to t = 1/180 s?

As we know that current is defined as rate of flow of charge

so by rearranging the equation we can say

here we know that

here we will substitute it in the above equation

now here limits of time is from t = 0 to t = 1/180s

so here it will be given as

so total charge flow will be 0.44 C

b.transmitters send radio waves, and receivers capture radio waves.
