circuit analysis and design‚ play a massive role in electrical engineering and without the correct application of theory and practise in unison‚ nothing can be achieved in a true engineering sense. Engineering requires theory to develop and test constraints while also requiring practical application of theory in order to determine tolerance and practical results for industry purposes. The ability to analysis a circuit gives a potential electrical engineer the ability to learn how to problem solve

circuit that described below which perform this job automatically. This circuit employed the output from an uncomplicated light/dark activated circuit and oblige a relay in its output which can be further attached to switch ON/OFF a street light and electrical application in a household also. Many of the people have a phobia of darkness‚ so to assist them in such situation‚ we have explained a simple circuit . It will automatically turn on street light in the way of LED’s or bulb coupled with relay‚

connected in parallel with the basic meter. The basic meter inside an analog ammeter has an intrinsic resistance‚ Rm‚ which is essentially small enough to sanction specific amount of electric current that will cause a full-scale deflection; though most of the time it becomes inefficient in producing current reading due to excessive electric current‚ thus shunt resistors provide additional resistances that would complement the additional amount of current. 3. What device is used to extend the range of

in. A source of electricity‚ such as a battery‚ provides electrical energy in the circuit. Unless the circuit is complete‚ that is‚ making a full circle back to the electrical source‚ no electrons will move. There are three essential parts to a true circuit. These include electrical devices. An electrical device is a device that resists the flow of energy. Another electrical device that a successful circuit must have is a source of electrical energy. An example of this is performed when you plug a

ascertained of a metal wire and thus find the resistance of the wire by deriving the inverse of the gradient of the graph. Skill: Planning & Designing Theory: Resistance is a property of any object or substance to resist or oppose the flow of an electrical current. The quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. This is according to Ohm’s law. The unit of resistance is the Ohm which has the Greek letter

Ohm’s Law Lab Report Number Three Quyama T. Wheeler @02669651 Partner: Munah Kaye Amber Frazier Objective: To demonstrate Ohm’s law and to determine the resistance of a given resistor. Theory: Ohm’s law is the assertion that the current through a device is always directly proportional to the potential difference applied to the device. Electric current is the moving of charges from a higher potential to a lower potential. Wires of different material (a copper wire versus a silver wire‚ for
