In which type of transistor does current flow?
And the answer depends on the type of transistor in use. In an NPN transistor, current actually flows from the collector to the emitter. In a PNP transistor, it’s exactly the opposite. In a PNP transistor, current flows from the emitter to the collector.
How does current flow through transistors?
We know that in transistors and diodes, electric current is carried by both free electrons and holes. Free electrons and holes travel in opposite directions. For example, if free electrons flow from left to right then the holes will flow from right to left.
Which transistor current formula is correct?
The Transistor current formula is IB=IC+IE. In general, the transistors are widely userd to ampligfy current and so undergo in an examination. It is asked to fill the current or collector current on the gain.
In which type of transistor the current flows in at the collector and out at the emitter?
NPN Transistor
NPN Transistor Example No1 One other point to remember about Bipolar NPN Transistors. The collector voltage, ( Vc ) must be greater and positive with respect to the emitter voltage, ( Ve ) to allow current to flow through the transistor between the collector-emitter junctions.
Which current equation is correct for a BJT transistor?
Bipolar Transistor Configurations
| Characteristic | Common Base | Common Emitter |
|---|---|---|
| Phase Shift | 0o | 180o |
| Voltage Gain | High | Medium |
| Current Gain | Low | Medium |
| Power Gain | Low | Very High |
What is transistor current?
This current consists of two constituents – Hole current (IhE) and Electron current (IeE). IeE is due to passage of electrons from base to emitter and IhE is due to passage of holes from emitter to base. Normally, the emitter is heavily doped compared to base in industrial transistor.
