Electronics Engineering

There are 2 types of CRO probes a. Active Probes (9 Megaohms) b. Passive Probes - hig voltage probe (10 to 1000 Megaohms)

In simple terms, if flux density increases, then field strength increases and vice versa. The flux density is equivalent to field strength times with a variable.

These are the Class codes for CTs used for protection purposes.

A Zener Diode will continue to show its breakdown characteristics until it gets fried...
for example a 5 volt zener will get fried at a breakdown voltage of about 6 volts..this happens because of the large amount of current flowing through the small diode which unfortunately the diode cannot handle.

Plastic Tubing.

The base of a transistor is basically a diode wich follows an exponential curve at very low level it display an almost infinite inpedance but at hi lelvel any additional diode current will not increase its voltage drop therefore a nominal value is assigned of .6v to .7v

Common mode input signal is a term associated with Differential amplifiers.There would be two input signals in a diff. amplifier.The common component of these two signals is called common mode input signal.ie.if V1 and V2 are the two input signals then (v1+V2)/2 is the common mode input signal.Also |v1-v2| is the difference mode input signal.

In a computer there are many A/D converters that put analog into digital. This signal is what is usually then led into an op amp which in the right configuration can be designed into an integrator or differentiator which is then used to solve differential equations.

A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.

• Have Low Shear strength: They can be 'torn' easily.

• The Techniques and the Set-ups used in the production of Carbon Nano tubes are very Expensive and very less Efficient.

. These are:

(i)Arc discharge

(ii)Chemical Vapor Deposition (CVD)

(iii) Laser Ablation

(iv)Electrolysis

• When inhaled, their interaction with the Microphages present in the lungs is similar to that with Asbestos fibers, hence may be seriously hazardous to human health.

It is often used in fabricating structures out of aluminum. Antennas and machinery enclosures are examples I am personally familiar with. Aluminum is tough to braze any other way, because you have little latitude with temperature. The brazing alloys that work with aluminum start to flow at temperatures that are very close to destructive for aluminum, especially in the presence of atmospheric O2. Temperature in dip brazing can be very tightly controlled.

Wire. conductors. Wire made into a coil, an inductor.

the physical energy is converted into electrical signal it's the principle of LVDT

Unipolarpulse waveforms consist of an applied anode potential during the on-period and an open-circuit potential during the off-period.

Moves it out of area

This question actually is unanswerable.

A DS3 or T3 has 28 DS1 or T1's.

A E3 has 16 E1's

There is no comparison between the two. A DS3 moves data at 45Mbps an E3 is 34 Mbps. they can not directly connect together. This includes their subrates. An E1 can not connect directly to a T1 without a converter.

even though a resistance is not connected in a circuit, it would practically have small resistance due to its components.so practically a LC circuit dosent exist..only a RLC circuit exists

Carries multiple signal on a signal medium.

it is more preferable over center tapped rectifiers because you dont have to use special centre tapped transformer that has larger secondary windings thereby reducing the size and cost

it also has another advantage by the use of 4 diodes i.e. peak voltage sustained by each diode is half of that sustained by the diodes in center tapped system that uses only 2 diode. thus lifespan of bridge type rectifier is more.

You can, but the available power will only be about half of rated, and the frequency response will be slightly different. Better would be to connect two 8 ohm speakers in parallel, making an equivalent 4 ohm speaker.

Because not all the logic gate have what the circuit needs to complete the operation
