Graph II is an Euler circuit because all vertices have even valence. 5. In order for a circuit to be an Euler circuit‚ each path must be covered once and only once. Since some edges in this graph have been covered twice‚ this graph cannot be an Euler circuit. 6. This graph is an Euler circuit. Each edge has been covered once and

In Unit 5 Activity 2 we were asked to predict and then find the brightness and flow rate of a closed circuit with a three cell battery pack‚ a long bulb‚ a capacitor parallel to the long bulb‚ and a round bulb. I originally predicted that the round bulb would be brighter when the circuit was first closed and when the circuit reached a steady state‚ and that the wire between the round bulb and the negative side of the battery would have a higher flow rate than the other wires. However‚ in the steady

voltage must be converted into a DC voltage with the right value and degree of stabilization. Figures 1 and 2 show the simplest rectifier circuits. In these basic configurations the peak voltage across the load is equal to the peak value of the AC voltage supplied by the transformer’s secondary winding. For most applications the output ripple produced by these circuits is too high. However‚ for some applications - driving small motors or lamps‚ for example - they are satisfactory. If a filter capacitor

This board is to be used for educational purposes in the Communications Lab at Princess Sumaya University College for Technology. This project includes: 1. Analysis and description for the main features of each of the modulation schemes. 2. Design and implementation of the electronic circuits for each of the three systems. 3. Design and implementation of a

Interpretation of Results As observed by the group in a normal diode circuit placed in a forward bias generates a sinusoidal output wave. In order to trim the output waves‚ that are a sinusoidal wave‚ to be generated‚ a clipper circuit was made with the use of diodes. The limiting level of a clipper circuit is the barrier potential of the diode in use. A diode clipper that trims down the positive half cycle input of a wave signal is as positive limiter. The output signal will retain the original

that any resistive circuit or network‚ no matter how complex‚ can be represented as a voltage source in series with a source resistance. It is used to simplify the load analysis of series-parallel circuits. 2. What is VTH ? How is it measured? Thevenin voltage. In a series-parallel circuit is the voltage present at the output terminals of the circuit when the load is removed. Even though it has a new name VTH is nothing more than the no-load output voltage VNL for the circuit. Vth can be found

Generation did not advance as much as most people hoped‚ but eventually‚ the "Third Generation" was brought about by the invention of integrated circuits in 1958. Integrated circuits replaced transistors‚ and many computer languages came out in this time. Many more computer companies were born during this time‚ and eventually this led to personal computers for everyday use. Microprocessors introduced the beginning of the "Fourth Generation" and a time where computers were in almost every house.
