As the name certifies unipolar is having two types of carriers i.e holes and electrons but in the operation of the devise only one can take part in the mobility i.e negatively charged electrons or holes but in contrast to this in bipolar both two participate in the carrier.
bipolar devices use both majority and minority current carriersunipolar devices use only majority current carriers
diode is unipolar
no. its unipolar
Bipolar dc involves both majority carrier and minority carriers for conduction while unipolar requires only majority carriers or minority carriers during conduction. point of view based on electronics devices.
FETs can be called UNIPOLAR devices because the charge carriers that carry the current through the device are all of the same type i.e. either holes or electrons, but not both. This distinguishes FETs from the bipolar devices in which both holes and electrons are responsible for current flow in any one device.

I believe that a unipolar lead is one with a single lead while a bipolar lead is one with multiple or 2 or more leads.
Bipolar depression refers to frequent mood changes between depression and mania, the focal point of Unipolar depression is the negative emotions and feelings that an affected individual experiences. The unipolar indicates that the depression does not alter between the two mood states.
the unipolar devices are those which conducts the current in one direction only or in which the current flow due to majority carriers only
The efficiency of a bipolar stepper motor compared to a unipolar motor has to be determined by the individual. If you are using the motor in a high speed situation, the unipolar motor is more efficient in those situations. For lower speed situations, the bipolar stepper motor is more efficient. Unipolar motors will have less torque at lower speeds, while bipolar motors will have less torque at higher speeds.

The sensory neurons in our body have different shapes but most are unipolar-shaped. Neurons can either be unipolar-, bipolar- or multiparty-shaped depending on their function.
Unipolar is more common, it's also known as clinical depression or Major Depressive Disorder. Bipolar (specifically Bipolar 1) is much more severe, although both disorders may become severe, Unipolar is still more common.
