Because two diodes is not a transistor. There is an interaction between the junctions in the transistor, because of their proximity, that you don't get in the two diodes. The only use of modeling a transistor as two diodes back to back is to test a transistor with a multimeter as a quick go-nogo test for basic operability.
Two types used at microwave frequencies are gunn and PIN diodes.
Anode and Cathode.
there are two diodes there but to use them as rectifiers never
Using two double diodes in a bridge circuit is not advisable because it can lead to unbalanced current distribution and potential failure of the circuit. A bridge rectifier requires four diodes to ensure that both halves of the AC waveform are utilized effectively, allowing for proper rectification. With only two double diodes, you may end up with insufficient paths for current during one half of the AC cycle, resulting in poor performance and inefficiency. Additionally, the configuration may not adequately protect against reverse voltage, risking damage to the diodes.
An antiparallel is a line which forms equal angles with two other lines but in opposite directions.
Antiparallel refers to a configuration where two molecules or structures run in opposite directions. In terms of DNA, antiparallel describes the orientation of the two strands running in opposite 5' to 3' directions. This allows for complementary base pairing to occur between the strands.
No, single stranded DNA molecules aren't considered antiparallel. Antiparallel refers to the orientation of the two strands in a double-stranded DNA molecule, where one runs 5' to 3' and the other runs 3' to 5'. Single-stranded DNA is usually unidirectional and doesn't have a complementary strand to be antiparallel to.
Yes, DNA is antiparallel. This means that the two strands of the DNA double helix run in opposite directions, with one strand running 5' to 3' and the other running 3' to 5'. This antiparallel arrangement allows for complementary base pairing between the strands.
a diode is a device that alows current to flow in one direction you have power diodes which are used in rectification processes and high current operations but the two main families of diodes are solid state diodes or valve operated diodes.
Antiparallel forces are forces that act in opposite directions along the same line of action. This means that the forces are equal in magnitude but opposite in direction. In a free-body diagram, antiparallel forces are typically represented using arrows pointing in opposite directions along a straight line.

There are several types of diodes; the only thing they have in common is that they have two electrodes - hence the name.
Anode and Cathode.
In the context of magnetic fields, parallel alignment means that the magnetic fields of two objects are pointing in the same direction, while antiparallel alignment means they are pointing in opposite directions.
You cannot build a transistor with two diodes. Even though the static junction characteristics of a transistor "looks like" two back to back series diodes, there is a relationship between the two junctions that cannot be matched by just connecting two diodes together.
