Is the motion of a charge across junction momentum conserving ? Why or why not ?

ls the motion of a charge across junction momentum conserving ? Why or why not ?

A charge is moving across a junction, then

A charge is moving across a junction, then

The kirchoff's first law (sum i=0 ) and second law (sum iR=sum E) where the symbols have their usual meanings are respectively based on (A) Conservation of charge conservation of momentum (B) Conservation of energy conservation of charge (C) Conservation of momentum conservation of charge (D) Conservation of charge, conservation of energy

Momentum||Laws OF momentum conservation

Assertion: When PN -junction is forward biased then motion of charge carriers at junction is due to diffusion. In reverse biasing. The cause of motion of charge is drifting. Reason: In the following circuit emitter is reverse biased and collector is forward biased.

Momentum || Conservation OF Momentum

Momentum || Conservation OF momentum

In planetary motion, the angular Momentum conservation leads to the law of
