Problem 3.12

The speeds in this example are the same as in Example 3.11. Why isnt the angle the same as before?

Step-by-Step Solution:
Step 1 of 3

 Voltage drop across a resistor is always positive.  Power is always dissipated by a resistor.  For loop problems, if the direction of current is given, draw the loops in that direction.  Current flows from higher to lower voltage  When current flows from + to – then power of the source is + (Power is said to be dissipated)  When current flows from – to + then power of the source is – (Power is said to be supplied)  A complete circuit is required for current flow. No breaks.  Diodes and transistors are some examples of components that don’t follow Ohm’s law.  Voltage across elements in parallel are equal  Current across elements in series is equal  For op amp problems, check for negative feedback. Establish V­ = V+ then do a node equation either at v­ or v+ depending on which one the negative feedback is connected to.  If current is going into (I_0 = negative current) an op amp from the current output terminal then the op am is said to be sinking. If current is being supplied (I_0 is positive) by op amp then it is said to be sourcing.  Non­ Inverting op amps draw current from sensors they are connected to.  Inverting op amps do not draw current from sensors they are connected to, therefore can supply more current than non­inverting op amps  Inverting op amp formula : Vout/Vin = ­R2/R1  Non­Inverting op amp formula : Vout/Vin = 1+R2/R1  Vout/Vin is called “gain”
