 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”
