FAQ

What is the Back EMF?
The Back emf opposes the current which causes it in any dc machine. Back emf refers to the voltage that is generated in an inductor or a coil of wire when the current flowing through it changes. Back EMF is usually measured using the Volt for Electric Potential. Note that the value of Back EMF is always negative.
Can the Back EMF be negative?
Yes, the Back EMF, measured in Electric Potential can be negative.
What unit is used to measure Back EMF?
Back EMF is usually measured using the Volt[V] for Electric Potential. Millivolt[V], Microvolt[V], Nanovolt[V] are the few other units in which Back EMF can be measured.
