• Bipolar disorder
  Bipolar disorder
  Bipolar disorder or bipolar affective disorder, historically known as manic–depressive disorder, is a psychiatric diagnosis that describes a category of mood disorders defined by the presence of one or more episodes of abnormally elevated energy levels, cognition, and mood with or without one or...
  
  
  • Bipolar I disorder
    Bipolar I disorder
    Bipolar I disorder is a mood disorder that is characterized by at least one manic or mixed episode. There may be episodes of hypomania or major depression as well...
    
    
  • Bipolar II disorder
    Bipolar II disorder
    Bipolar II disorder is a bipolar spectrum disorder characterized by at least one hypomanic episode and at least one major depressive episode; with this disorder, depressive episodes can be more frequent and are more intense than hypomanic episodes...

    Bipolar NOS
    Bipolar disorder NOS is a diagnosis for bipolar disorder when it does not fall within the other established sub-types Sub-types of bipolar are part of the bipolar spectrum. Bipolar NOS is described as drastic changes in mood, it is considered a mood disorder.This disorder usually occurs during...
    
    
• Bipolar spectrum
  Bipolar spectrum
  The bipolar spectrum refers to a category of mood disorders that feature abnormally elevated or depressed mood. These disorders range from bipolar I disorder, featuring full-blown manic episodes, to cyclothymia, featuring less prominent hypomanic episodes, to "subsyndromal" conditions where only...

• Bipolar electric motor
  Bipolar electric motor
  A bipolar electric motor is an electric motor with only two poles to its stationary field. They are an example of the simple brushed DC motor, with a commutator. This field may be generated by either a permanent magnet or a field coil....

• Bipolar signal
  Bipolar signal
  In telecommunication, a bipolar signal is a signal that may assume either of two polarities, neither of which is zero.A bipolar signal may have a two-state non-return-to-zero or a three-state return-to-zero binary coding scheme....
  
  
• Bipolar violation
  Bipolar violation
  A bipolar violation, bipolarity violation, or BPV, is a violation of the bipolar encoding rules where two pulses of the same polarity occur without an intervening pulse of the opposite polarity. This indicates an error in the transmission of the signal.T-carrier and E-carrier signals are...
  
  

Transistors

• Bipolar junction transistor
  Bipolar junction transistor
  |- align = "center"| || PNP|- align = "center"| || NPNA bipolar transistor is a three-terminal electronic device constructed of doped semiconductor material and may be used in amplifying or switching applications. Bipolar transistors are so named because their operation involves both electrons...
