Instead of describing, why not upload a picture of what you have, and it helps to analyse?how do i detect? is it waveform on 1st quadrant is equal to P type and waveform on third quadrant is equal to n tpye?
i mean as to determine pnp or npn diode
hi Shermaine,
A transistor has a pn and a np junction.
In a pnp transistor the 'n' section is sandwiched between the two outer 'p' sections.
With a npn transistor its the 'p' section in the middle of the sandwich.
Is this what you mean.?![]()
The PNP transistor is in the 3rd quadrant and the NPN in the 1st quadrant on a curve tracer.how do i detect? is it waveform on 1st quadrant is equal to P type and waveform on third quadrant is equal to n tpye?
