DC CIRCUITS
What are the 2 types of currents
AD - DC
What is Coulomb's First law
Say first law
What is Faraday's law
Say faraday's law
What is Feedback
process of feeding a part of the output back to the
input
What is the power supply rejection ratio
abilility to reject noise or ripple oncuring at the input
PSRR= AVin/About
Ideally high
I = V/R
What is electric flux
the measure of the flow of electric field perpendicular through an area
What is lenz' law
say lenz' law
Types of feedback?
negative and positive
What is unity gain frequency
frequency ofsignal at wie the gain is 1
What is resonance
Tendency of a system to absorb more energy
What are the capacitor applications name all 3
Decoupling, filtering, energy storage
coils are closer to each other without shielding
it is possible for the two inductors to couple
What are the types of oscillators and what are they
generate AC
produced by using a positive feedback
oscillatortype
1 Feedback oscillators
2 Relaxation Oscillators
What are multivibrators and what are their states and types
relaxation oscillator chat that produces oscillation between
high and low states at the output
uses two active components coupled is such a way that
one is conducting while the otheris in cutoff
States
1 Stable
state will not change unlessdisturbed
2 Quasi stable
state remains unchanged only for a certain
period of time
BI STABLE MONOSTABLE ASTABLE
Types of electricity
Static and dynamic
What is Magnetism
Property of material that can produce /conduct magnetic lines of force
Describe Electromagnetism
magnetism produced by an electric current
Hans Christian Oersted
electric current can be produced by moving a magnet
near the circuit
Michael Faraday and Joseph Henry
Michael faraday and Joseph Henry
Changing e field creates h field Maxwell
What is the Piezoelectric effect
ability to generate voltage in response to applied
mechanical stress
What is Moore's law
The number of transistors on a microchip doubles
almost every triggersthing the cost of computer is
halved or maintained
Name the two laws of electricity
Say the answer
Laws of Magnetism?
Say laws of magnetism
What is the equation for magnetic flux density
B=yH
What is microelectronics
electronic systems made up of extremely small electronic parts or elements
