    Best way of explaining PN Biasing to a friend?

    Hey everyone, got a quick question Last semester, I ended up taking a solid state physics course and surprising myself I ended up getting a B- in the class (most of the other people ended up getting D's). For the most part much of this due to the 'memorize the equation' and 'plug and chug'...

    Engineering Boolean and truth table for circuit

    Perhaps the best way to look at the logic is 'what path will the current take when either transistor is enabled. Remember when no current is flowing, the potentials across either side are the resistor are the same. Hope that provide a clue.

    Nodal Analysis of a Voltage Dependant voltage source, no pretty answer

    Homework Statement five branches left most branch: 50 Volt source second left most: 10 ohm resistor shared branch between the second left most branch and center: 10 ohms (Voltage drop from left to right= V delta) center branch: 30 ohm resistor between center and second right...

    Superpostioning of an inpendent voltage and current source with depend

    As a followup, I decided to upload the problem with my explanation to the problem. Hope it provides help to anybody needing some guidance (and thanks again gneill)

    Superpostioning of an inpendent voltage and current source with depend

    If there was a thanks button, I just clicked it for you. Thanks for noting the correlation between the i delta and i1 currents

    Superpostioning of an inpendent voltage and current source with depend

    Homework Statement 3 branches, Indpendents are a 15 Volt source (left most branch) in series with a 2 ohm resistor (current that flows from left to right though this resistor is 'i delta'), Middle branch contains a 5 ohm resistor in series with a current controlled voltage source (3 ohms * i...

    Auto/Motor Feasibility of a carbon fiber chassis (DIY car design)

    Hey everybody, a couple years ago, I came across the top gear video for the Arial atom: a ~1000 lbs road legal 'go-cart' with a supercharged I-4 engine with a power to weight ratio of 600HP/Ton. Even though the body is already light, I would love too (once I get the time and resources) build...

    How to calculate energy used in a variable speed drive

    In a math model, the energy consumed is the area under the curve of a function, in this case of unit energy per time. For a full throttle motor, the area under the curve is rectangular. For a variable drive, that unit energy per time can vary, resulting in a differing amount of power consumed...

    Solving Complex Power with a 400-V, 100-Hz Source and a Load of 400+j30 VA

    For the Apparent Power, check you decimals for Power factor, remember arc-cos

    Physics of River Crossing: Solving for Angle and Component Velocity

    if your familiar with the real and imaginary plane system, it may look a little bit easier to handle. There are two vectors, VB and VR (Vectors always contain a magnitude and a direction). The interaction of this two vectors will create a new vector dependent upon the angle difference and...

    What is the displacement and component analysis of a cat climbing a tree?

    the to approaching this problem is knowing some differentiation. As an example, if you differentiate distance with respect to time, you create a rate of change of distance dependent upon time, more commonly know as velocity (ie miles per hour...). If you differentiate again, you then have...

    Center of Mass of a Triangle (uniform)

    It does, the centroid is an average of the three coordinates, ( (stigma x) /3, (sigma y)/3). since its an equilateral triangle, the angles are all the same, and will all have the same terminal vector of 30 degrees (~0.5 rad) with equal length A good way to see it is (using a triangle of 2...

    Engineering Black box Conumdrum: CL or LC order in a RLC circuit

    Hey everyone. Since it is nearest the end of the summer semester for the Lab component of my classes, Our professor is having do the 'Black Box' project. From the information he gave us, there are three component in a L-configuration, an inductor, capacitor, and a resistor. The Box itself had...

    Mastering Pump Control: Tips for Success | Reservoir, Bucket, and Float Switches

    if your familiar with microprocessor programing, its a case of having a conditional loop dependent upon if the bucket is full or not. Some psudo-code int Fill_Pump=10; int Drain_Pump=11; int Bucket_Level=12; //Defines input and output pinsint Bucket_Value=13; //Memory Location to store Analog...
