Tuesday, October 19, 2010. Combining Resistors and Voltage/Current Division. Series Resistors: If resistors are connected in series with each other, that is if they share the same node back-to-back exclusively, than the sum of their resistance values is the equivalent resistance and both resistors can be replaced by the equivalent resistor. Req = R1 R2 . Rn. Req = (R1)(R2) / (R1 R2). Vn = [Rn / (R1 R2 . Rn)] * V. For other classes/notes in the engineering field click here. Kirchhoff's Voltage Law(KVL): t...

Thermodynamics: October 2010
http://thermodynamics1.blogspot.com/2010_10_01_archive.html
Tuesday, October 26, 2010. Potential - PE = mgz (mass*gravitational acceleration*vertical distance). Kinetic - KE = .5mV 2 (.5*mass*velocity squared). Total Energy equals the sum of internal energy potential energy kinetic energy. E = U PE KE. Energy flow rate (time rate of energy) is equal to the mass flow rate multiplied by the mechanical energy per unit mass. E(dot) = m(dot) * e. M(dot) is the mass flow rate. m(dot) = (rho) * V(dot) where V(dot) is the volume flow rate. Efficiency = output / input.

Circuit Analysis: Laws
http://circuit-analysis-1.blogspot.com/2010/10/laws.html
Tuesday, October 19, 2010. Ohm's Law: voltage across a resistor is proportional to the current through it. Voltage = current multiplied by resistance. V = iR. Kirchhoff's Current Law(KCL): the sum of currents entering a node is zero. Kirchhoff's Voltage Law(KVL): the sum of voltages around a loop is zero. Branch: any single element (example: resistor, voltage source, etc.). Node: point of connection between two or more branches. Loop: closed path in a circuit. Subscribe to: Post Comments (Atom).

Control Systems: January 2011
http://control-systems-1.blogspot.com/2011_01_01_archive.html
Wednesday, January 19, 2011. A control system is several components connected together to achieve a goal. There are two basic types of systems. Open Loop: an input is fed into a system and through the process of the system and a direct output is achieved. Closed Loop: uses a feedback loop to compare the actual output with the desired output and makes adjustments to the input to achieve the desired output. The Process of a control system consists of:. Plant: Example: car, drive train, flow of a fluid.
