many different pieces of equipment to one cable. That cable is typically a coax that is connected to a terminator‚ also known as a resistor‚ at each end that keeps the signal from “ringing.” This type of network is usually less expensive than other forms due to its lack of needing multiple cables. This can also lend itself to failure if the cable is cut or the resistor goes bad the whole network goes down and can’t be brought back until that cable is replaced‚ much more difficult than replacing a

ABSTRACT The effect of equivalent series resistance (ESR) of an output capacitor on the performance of a constant -on-time(COT)-controlled buck converter is studied and a pulse bursting phenomenon is revealed. It indicates that the ESR of the output capacitor is one of the key factors causing pulse bursting phenomenon in COT-controlled buck converters‚ and the critical ESR is derived via. It is pointed out that ‚ when the ESR of the output capacitor is smaller than the critical ESR ‚pulse bursting

Magnetic effect of electric current is one of the major effects of electric current in use‚ without the applications of which we cannot have motors in the existing world. A current carrying conductor creates a magnetic field around it‚ which can be comprehended by using magnetic lines of force or magnetic field lines. The nature of the magnetic field lines around a straight current carrying conductor is concentric circles with centre at the axis of the conductor. The direction of the magnetic field

What is a breadboard? A breadboard is used to build and test circuits quickly before finalizing any circuit design. The breadboard has many holes into which circuit components like ICs and resistors can be inserted. A typical breadboard is shown below: The bread board has strips of metal which run underneath the board and connect the holes on the top of the board. The metal strips are laid out as shown below. Note that the top and bottom rows of holes are connected horizontally while the

vehicle. The heart of the circuit is a 555 timer IC‚ wired as an astable multivibrator in the circuit. A 2N3773 high current transistor is also used in the circuit and working as a switch and it is derived from the output pin 3 of the IC through a 1K resistor. The IC generates continuous pulses on its pin 3 which makes the transistor switch ON and OFF continuously. When the transistor will be in the switched ON state the 12 volts from the battery starts passing through it and activate the lamps and in

adequately the changes that need to take place and ensure that they are effect in reaching the goal the organization is trying to achieve there are measures that need to be monitored and gauged. The change process needs to include possible opportunities‚ resistors‚ the organizations culture and the effect that the change can have on the culture‚ and future change initiatives. Once the change is determined implementation is needed‚ monitoring the change from beginning stages to the stage of change being successful

Hoang Ngo Lab 6 report Anita Dey Thursday 8am Abstract: We recently performed a liquid nitrogen experiment in finding the Latent heat of the substance. We isolated two parts of the experiment in order to find out how much evaporation of the liquid nitrogen was from the surroundings B and how much evaporation from the electricity G. 1. When a substance is undergoing a phase transition‚ more heat (energy) is being added to the Substance but its temperature (a way of measuring its energy) is not

How Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of
