    How Do You Solve for x in This Algebra Equation?

    First, put the terms with x on one side and the rest on the other side.Then, factor x out and divide both sides to have the x alone on one side.Finally,simplify.

    How Can Basic Algebraic Skills Be Applied in Electrical Engineering?

    Ok, take this example https://www.physicsforums.com/showthread.php?t=376316 Two important things you should know 1-http://en.wikipedia.org/wiki/Ohm%27s_law" 2-http://en.wikipedia.org/wiki/Kirchhoff%27s_circuit_laws" Using Ohm's and Kirchhoff's Current Laws, you will end up with...

    How Can Basic Algebraic Skills Be Applied in Electrical Engineering?

    I think it's not a good idea to pick a problem from EE problems. Because most of it are boring.

    Engineering Circuit with resistors. help me please

    If you transform the resistors you will lose the given information.To solve the problem,assign a current at every brunch and use KCL at every essential node.

    Why Can't I Solve for Is Using the Left Loop in Thevenin Voltage Problems?

    Because of the current source you can't apply KVL at that loop, unless you know the voltage across the current source However,this is simple circuit you can usehttp://en.wikipedia.org/wiki/Source_transformation"

    KCL Question: Determine Currents

    As I said before use the mesh analysis there are two meshes you will have two equations to solve http://en.wikipedia.org/wiki/Mesh_analysis or you can use Nodal analysis , which is better in this case http://en.wikipedia.org/wiki/Nodal_analysis

    Thermodynamic Processes: Ideal Gas Expansion and Compression

    Use the ideal gas equation To find the work you need only information about the volume and pressure

    Engineering Creating a 4 bit full adder logic circuit

    You can build it using 1- Combination of AND,OR and NOT gates 2- NAND or NOR 2- Decoder and 4 OR gate 3- Multiplexers

    Direction of work of block colliding with spring

    Work done on or by a system It depend on which reference your book choice some books take the work done on a system as negative and in other books positive

    Parallel/Series Circuit w/ Capacitors

    Two loads are in parallel if their terminals connected to the same two nodes ( they have the same voltage across the terminals) Hence, there are 3 nodes in this circuit

    KCL Question: Determine Currents

    Use mesh analysis and KVL

    Switching Algebra proof question

    all you need are distribution ,aa=a and a+a'=1 there is no need for DeMorgan or anything else

    Converting AND-OR expression to NAND-NAND?

    Keep in mind that in the logic diagram you will implement it in two-level NAND gate for example if you have this function f(w,x,y )=xy+xz+w In the first level you will have (xy)' , (xz)' , w' Then the second level [(xy)'(xz)'w']'=xy+xz+w
