What is electric circuit or electric network?

The combination of various electrical elements such as resistors, capacitors and inductors along with various energy sources such as voltage and current sources is called electric circuit or electric network. qb question bank

Define branch and node.

Branch: It is a portion of a circuit with two terminal connected to it. A branch may contain one or more elements.

Node: It is a junction of two or more branches.

Define bilateral and unilateral network.

Bilateral network: The voltage-currant relationship is same for current flowing in either direction is called bilateral network.

Ex. R, L and C

Unilateral network: The network has different relationships between voltage and current for the two possible directions of current.

Ex: Diodes, vaccum tubes

In a large city A, 20 percent of a random sample of 900 school boys
had a slight physicaldefect. In another large city B, 18.5 percent of a
random sample of 1600 school boys had somedefect. Is the
difference between the proportions significant?

A standard sample of 200 tins of coconut oil gave an average weight
of 4.95 kg with a standard deviation of 0.21 kg. Do we accept that
the net weight is 5 kg per tin at 5% level of significance?

Details On EC8252 Electronic Devices Question Paper

Why an ordinary transistor is called bipolar?
The operation of the transistor depends on both majority and minority carriers. So it is called bipolar device.

Collector region of transistor is larger than emitter. Why? EC8252 Electronic Devices Question Paper
Collector is made physically larger than emitter and base because collector is to dissipate much power.

Why is BJT is called current controlled device?
The output voltage, current, or power is controlled by the input current in a transistor. So it is called the current controlled device. EC8252 Electronic Devices Question Paper

Among CE, CB, CC which one is most popular. Why?
CE is most popular among the three because it has high gain compared to base and collector configuration. It has the gain about to 500 that finds excellent usage in audio frequency applications.

Define current amplification factor EC8252 Electronic Devices Question Paper
In a transistor amplifier with a.c. input signal, the ratio of change in output current to be the change in input current is known as the current amplification factor.

Why it is called field effect transistor?
The drain current ID of the transistor is controlled by the electric field that extends into the channel due to reverse biased voltage applied to the gate, hence this device has been given the name Field Effect Transistor.

Define Early Effect. EC8252 Electronic Devices Question Paper
A variation of the base-collector voltage results in a variation of the quasi-neutral width in the base. The gradient of the minority-carrier density in the base therefore changes, yielding an increased collector current as the collector-base current is increased. This effect is referred to as the Early effect. EC8252 Electronic Devices Question Paper
