Definition of low impedance medium impedance and high impedance?
Wiki User
∙ 15y ago
For instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.

Why emitter follower preferred to transforms as a impedance matching?
because it has high input impedance and low output impedance
Compared to bipolars FETs have-a high input impedance b low input impedance c same input impedance?
FET s have very high input impedance when compared with Bipolar transistors.
Which is better high input impedance or low input impedance and why?
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
Does a Digital Voltmeter have a high or low input impedance?
Digital voltmeter has high input impedence.
What is the Difference between low and high impedance relays?
It depends on the resistance level in that area if the soil have low resistance then they will use high impedance system and vice versa..so reason behind this have to reduce fault current.
Definition of low impedancemedium impedance and high impedance?
There is no precise definition, but for instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.
Are drum triggers high or low impedance?
V-Drums, for instance, have an output of 330 ohms, making them low- medium-impedance.
In a multistage amplifier input impedance is high and output impedance is low justify the statement?
no. input impedance is low & output impedance is high

What is the definition of low earth orbit?
An earth orbit that is lower to earth then both a medium and high earth orbit.
What type of transformer configuration will you select to design a high input impedance and low output impedance amplifier?
main volage
Does a Digital Voltmeter have a high or low input impedance?
Digital voltmeter has high input impedence.
