Is a lawyer a open or closed loop?
It depends. Which is more corrupt? -- An open loop or a closed loop? Whichever one is more corrupt, selfish, and greedy, then that is the one that befits attorneys.
Define open loop engine management as apposed to closed loop?
Yes i can anwer it.
What is the difference between Open loop vs closed loop fuel system?
What is the difference between 'Open Loop' and 'Closed Loop'? A: When the engine is first started, and rpm is above 400 rpm, the system goes into 'Open Loop' operation. In 'Open Loop', the ECM will ignore the signal from the Oxygen (O2) sensor and calculate the air/fuel ratio based on inputs from the coolant and MAF sensors, but mostly from a pre-programmed table in the memcal. The system will stay in 'Open Loop' until the following conditions are met: 1. The O2 sensor has varying voltage output, showing that it is hot enough to operate properly. (This depends on temperature) 2. The coolant sensor is above a specified temperature about 40oC/104oF. 3. A specific amount of time has elapsed after starting the engine. The specific values for the above conditions vary with different engines and are stored in the mem-cal. When these conditions are met, the system goes into 'Closed Loop' operation. In 'Closed Loop', the ECM will calculate the air/fuel ratio (injector on-time) based on the various sensors but mainly the O2 sensor. This allows the air/fuel ratio to stay very close to 14.7:1.
What are the disadvantages of closed loop systems?
its costly than open loop system and bulky, too.
What about sensitivity of a closed loop system?
Sensitivity of a closed loop system for a change in the system gain is 1/(1+GH)
What is closed control?
In industry closed control is a closed loop feedback where a pump or motor has an encoder or feedback device to keep the operation regulated.
What happens when there is a change in the magnetic field in a closed loop of wire?
It produces a current.
Electric rice cooker operation in open-loop or close-loop circuits?
if we set timimg for cooking rice then it is open loopbut thermostat in electric cooker can not give more temmp, than 100deg. so some microprocessor is controlling here .thus in this case it will act as closed loop system.
What is the difference between finite open loop gain and closed loop gain?
In a closed loop system the gain without the feed back loop being closed is called open loop gain!!! e.g if forward gain is "A" and feed back factor is "B" then open loop gain is "AB" and closed loop gain will be [A/(A+B)]
