Anonymous: why 3---no..i want only this answer..
GamingJAKE: cause
GamingJAKE: the rotation depends upon the load and speed
GamingJAKE: speed depend on V which is constant in dc motor
GamingJAKE: load restricts speed
GamingJAKE: so motor tries to automatically reach its basic speed
GamingJAKE: hence the magnitude remain constant
GamingJAKE: actually the concept is not much cleared
GamingJAKE: cause I am just 14 years old
GamingJAKE: sorry for that
