whye the current increases in the motor when the load on the
motor increases

Answer Posted / gajendran.al

When load on the motor increases, it tries slow down. This
reduction of speed reduces the back emf produced [which
acts as the current limiting impedance]. Due to this the
current drawn by the motor increases
