Confused About Transistors: Pi Hybrid & Small Signal Equivalents

AI Thread Summary
Pi-hybrid models are indeed used for small signal analysis in transistors. They serve similar purposes as T-small signal models, both representing the behavior of transistors under small signal conditions. Understanding these models is crucial for analyzing transistor circuits effectively. The discussion emphasizes the importance of grasping these concepts for academic success in electronics. Clarification on these models can significantly aid in studying transistors.

Hi everyone. I am starting to study transisors at Uni. and I am confuse in some main concepts. i thought about posting it here so someone can help me up. are pi hybrid signals equivalent circuits used with the same porposes as small signals equivalent circuits? or are pi hybrid signals, small signals??

sorry i know it might be sort of a stupid question. ill be very appreciated for any feedback

thankyou

Yes, pi-hybrid model is for small signals. Another commonly used and equivalent model is T-small signal model.
 
thanks for your reply zoki

very appreciated
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
