D.C series motor both armature and feild connected in series at noload condition current drawn by the motor is zero Ia=0 flux also zero. but very small amount of flux avalible because of residual magnetism

in series motor speed  =  N α Eb/Φ Eb almost conistant

                                 =    N α 1/Φ

At no load condition d.c series can be run as dangerously very high so d.c series motor
operated at load condition only

Stimulus diffusion is a type of expansion diffusion in which the idea is acceptable or adopted but not in its original form and expanded to culturally acceptable.

For example :

1. Mc. Donalds is also in India but not in beef. Indians culture will not accept beef and so it is with different forms like veg, non veg but the idea is same.

2. Yoga is an idea where in different regions use yoga for different reasons but the idea is same.
