Electronics Trivia 18

Determining the best pole:

  • specification  of system performance
  • practical considerations

DC motors is most affected by 

  • copper loss

In small induction =

  • energy is stored & released quickly 

Process w/c is not included in monolithic IC fabrication-

  • Die Casting

Change in magnetic field-  

  • Produces fluctuation in electric field

Reason why high range is use when voltmeter is connected in a circuit—

  • to prevent excess current through meter movement

Power loss due to corona is not proportional to space---

  • between conductors

Outstanding features of universal motor:

  • Highest output of kW/kg ratio

What gives OP amps immunity to noise immunity to noise:

  • Hysterises

JFET references point JFET – 

  • Source

It helps in energy conversion – 

  • counter emf

robotic arm w/c allows the robot to move, yaw,pitch and roll—

  • manipulator

it compose of passive components such as resistor and capacitor—

  • Film IC

place where the cathode in dry cell found – 

  • zinc container

gain of buffer amplifier—

  • unity

conductivity of semicon when there is light

  • increasing

fault connection—

  • faulty wiring connections

all odd harmonics—

  • square wave

A transistor that operates on a Non saturated switch eliminate

  • Storage Time.

The time required for Ic to reach 90% of its maximum level from 10 % level is 

  • Rise Time.

DE MOSFET differs from JFET 

  • generally because It has no PN Jnunction.

CMOS circuits are extensively in on – chip computers because of its 

  • extremely large packing density.

Nickel Iron Battery has active elements of 

  • Nickel Hydroxide; powdered Iron with its oxides; 21% solution of caustic potash.

A Transformer coupled Amplifier would give 

  • Impedance Matching.

When an emitter bypass capacitor in a CE amplifier is removed its

  • voltage gain is considerably reduced. 

A circuit that uses an integrator to convert a step wave to a ramp wave form is a

  • Miller Circuit.

A phototransistor is more like a conventional transistor except that in there case

  • it uses light energy to switch it on.

Before illuminating a PN Junction Photo Diode

  • it has to be reversed biased.

When an IC is formed by depositing the required devices of passive elements like resistors, capacitors and is interconnected on an insulated substrate

  • it is a Film IC

The emitter of a transistor is generally doped the heaviest

  • because it has to dissipate maximum power.

The difference between a J-K flip flop from a S-C flip flop is its 

  • Toggle Condition.

When a PN Junction is produced, the diffusion current would cause a 

  • Barrier Potential.

In the Operation enhancement only N – channel MOSFET, 

  • the value of its gate voltage is highly positive.

Silicon is Z = 14, its outer sub shell 

  • is half – filled.

OS Memory 

  • contains the bios that is read in when the computer is first started.
