How does an active voltage divider network for Photomultiplier work?

Conceptually, it's the same as a passive voltage divider but with buffer amplifiers on the outputs connected to each dynode - the primary purpose of this is that it decreases the source impedance so that current flowing into the dynodes does not affect the voltages applied to any significant extent.

What are the types of harmonic filters in ups?
Basically they are of 2 types 1) Active filter - For low voltage network 2)Passive filter
Is constant voltage source an active or passive element?
is active...and bilateral
Transistor is a linear or non linear circuit element?
it is not a passive device .y because it is used to amplify the voltage and current .so as according to the definition of active device is the device which is used to amplify the current r voltage .hence transistor is a active device.
What is the use of voltage divider circuit?
Biasing-Application of suitable DC voltages to operate our amplifiers in desired region of operation(say active or saturation or cut-off region) complying our needs.However in order to maintain a constant Q point irrespective of various external factors,hence it again comes to the need for biasing that compensates the change in external factors suitably thereby maintaining a constant Q-point. Voltage divider bias or self bias is a process of suitably biasing amplifier by connecting two resistors in series in the answer. By proper selection of resistors R1 and R2, the operating point of the transistor can be made independent of β.
List two examples of categories for both passive and active network security attacks?
passive attacks : footprinting, trashing active attacks : sniffing, social engineering
What is an active electrical network?
The electrical network which has its own energy sources like current or voltage sources within the circuit is called as an active electrical network

What is linear bilateral active networks?
If I divide the term into words as (Passive + Linear + Bilateral ) Network then it would be easier to understand. 1st of all, Passive Network is a network that includes **passive electrical / electronic components. Then, Linear Network is consists of passive electrical / electronic components whose parameters such as resistance, capacitance or inductance are constant with respect to current or voltage and in such network each voltage or current source act independently of each other. After that, Bilateral Network is the network in which the magnitude of current remains the same when the voltage polarity is reversed. So, A Passive linear bilateral network includes passive components that exhibit linearity and at the same time magnitude of current is independent of the polarity of voltage. ** Passive electronic components are Resistor, Inductor or Capacitor, they by themselves are not capable of amplifying or processing an electrical signal.
What is the difference between active attacks passive attacks in network?
What is the difference between active attacks passive attacks in GSM network?
What is active directory services?
Active Directory service is used to store information about the network resources across a domain and also centralize the network.
What is the lowest stimulus voltage that induces active force in the skeletal muscle?
It is called the threshold voltage and is around -70 mvolts.
Definntion of active elements?
An active electronic element is one that can produce voltage gain or current gain.
How many social network sites are active?
I know of one: http://www.sailorbits.com . Its active
What is doide?

What is active topology in network?
The Active topology functionally allow you to make element inactive (and chnage them back active again).
According to Theremins theorem any linear active network can be replaced by a single voltage source?
You are confusing "Thévenin" with "Theremin." Léon Charles Thévenin (1857-1926) developed a theorem for linear electrical networks stating that any combination of voltage sources, current sources and resistors with two terminals is electrically equivalent to a single voltage source and a single series resistor.
