Voltage Gain of Inverting op amp
Vout/ Vin= -Rf/Rin
Voltage Gain of Non Inverting op amp
Vout/ Vin= 1 +Rf/Rin
Vout of amp
Vout= A0(V+ - V-)
Summing amplifier
Vout = -(V1+V2+V3) ifa ll resistors have same value
Vout = -(Rf/R1V1 + Rf/R2V2+ Rf/R3V3)
Casade amplifier overal votage gain

Electric charge DFS
Q=It
Q charge / C COLOUMB or Ampere per sec
I current
t time
Potential Diff DFS
The amount of electrical energy converted from electric to other forms of energy per coulomb of charge passing from one point to another
V=
W/Q
=IR
V formulas
V=IR
P=IV
P= I²R
Resitivity
rho= RA/L
Resistance
R=V/I
R=rhoL/A
Drift velocity
Using I=nevA
v=I/neA
Capacitance
C=V/Q
Ohms law
the current flowing through a conductor is directly proportional to the pd provides there is no change in conductor properties
V=IR
Kirchoffs 1st law
the sum of the current flowing into a circuit is equal to the sum of current flowing out
I1 = I2 + I3
Kirchoffs 2nd law
The algebraic sum of the emf is around any lopp of a circuit is equal to the sum of the pds around the loop
