What are the classification of amplifiers according to transistor configuration?
common emitter using fixed bias
Why emitter bias is more stable than fixed bias?
negative feedback
Why the impedance of infinite bus bar is zero?
...because it is an infinite bus bar, meaning it can supply infinite current. By Ohm's law, since the voltage at the bus bar is fixed, to have infinite current, you must have a zero impedance.
When to use fixed -order quantity model over fixed-time period model?
Use the foq model when inventory is more important or expensive as you do not want to have stock out for this particular inventory whilst fop is used when inventory requires high maintenance costs
What is a common engineering problem with all big machines?
They have to be fixed up when they break and cost a lot of money.
Is the output impedance of common emitter a fixed quantity?
A: NO it is not fixed it depends on the load line
What are the classification of amplifiers according to transistor configuration?
common emitter using fixed bias
What are the applications of fixed bias circuit?
low input impedance
Why emitter bias is more stable than fixed bias?
negative feedback
What are the applications of fixed bias amplifier circuit?
low input impedance
Definition of fixed order quantity system?
A fixed order quantity system is the arrangement in which the inventory level is continuously
What is the need of impedance matching?
Impedance matching is setting the input impedance (load) equal to the fixed output impedance (source) to which it is connected, in order to maximize the power transfer.Matching is obtained when Zload = Zsource.In audio and sound engineering we have really no impedance matching. There is only impedance bridging. Zload >> Zsource.Scroll down to related links and look at "Impedance bridging - Wikipedia".
What is a fixed quantity of light energy?
Wikipedia says that a photon is a fixed quantity of light energy.
Is the moment of inertia a fixed quantity?
no
What is measerment?
the comparison of unknown quantity against fixed with known quantity is called measurement.
It has a definite volume but has no definite shape what is the answer?
A fixed quantity of liquid at a fixed temperature and pressure.
Voltmeter DMM or VOM has the higher loading effect?
The VOM has the higher loading effect, because it has a lower impedance. It is typical for a VOM to have an impedance of 20K ohms per volt while the DMM has a fixed impedance of 10M ohms or 20M ohms.
