ANSWER-FLOW TOWARDS THE GENERATING STATION
THREE THINGS NEEDED TO PRODUCE ALTERNATING CURRENT - ANSWER-1.
CONDUCTOR
2.MAGNETIC FIELD
3. RELATIVE MOTION BETWEEN THE TWO
POLARITY IS WHAT - ANSWER-DIRECTION OF CURRENT FLOW BETWEEN
POSITIVE AND NEGATIVE VOLTAGE
STRENGTH OF THE VOLTAGE PRODUCED DEPENDS ON THREE PRIMARY
FACTORS - ANSWER-1. NUMBER OF TURNS IN THE COIL OF THE WIRES
