A transmission system at a radio station uses an oscillator
to convert a direct current into a high frequency alternating current. Direct
current or DC is the current in which the flow of the charge is one
directional. In case of alternating current or AC, the flow of the charge
reverses direction after a period of time.
In regards to the second
question, a unit for measuring frequency is the hertz. So the correct answer to
the given question is option “B”.
