Precision Rectifier: Get Answers to Your Questions

AI Thread Summary
The discussion centers on the operation of a precision rectifier and the relationship between output voltage (Vout) and the input voltage (E). Participants clarify that Vout equals E because the op-amp compensates for the diode forward voltage drop through negative feedback, effectively nullifying its impact on the output. The confusion arises from a lack of understanding of op-amp characteristics, particularly how they function in this circuit. The precision rectifier design allows for accurate rectification without the typical diode voltage drop affecting the output. Understanding op-amp behavior is crucial for grasping the precision rectifier's functionality.

hey,dude,i m confusing about the precision rectifier...why the Vout =E,my question is why the Vout=E - V(diode) ?why the Vdiode does not take into account when finding Vout?here the attachement of the precision circuit diagram..

The op-amp compensates for the diode drop as part of the negative feedback.
 
oic~~~~quite confusing about that because i haven't learn the characteristics of opamp.anyway.thx ya~
 

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
