Electrical technology – assignment 4 Properties of electrical materials and Effective use of technology P.5. Describe the properties and a typical application of a solid and a liquid or gas electrical conductor. A conductor is a material that allows free movement of electrons and therefore allows easy flow of electricity. Most conductors are metals. A common metal used as a conductor in electrical technology is aluminium. It is used quite a lot as it cheap‚ lightweight and in abundance compared

of a transformer (see Figures 1 &2). If it is desired to find the parameter of the exact equivalent circuit (see Figure 3) it is customary to assume R1=a2R2 and X1=a2X2. By making this assumption we can decompose the values of the equivalence resistance and reactance into the primary (winding 1 or high voltage side) and secondary (winding 2 or low-voltage side) components.

a series connection as shown in Figure 5.1 to determine the whether the divider rule is correct or not by using theorical method. We set the power of generator to 9V and put 3 resistors in the circuit and label it as R1‚ R2 and R3‚ each with the resistance of 1k‚ 3.3k and 4.7k. We also added a voltmeter reading between each of the part of resistor to take the voltage reading. After all components in the circuits are connected correctly we click the green run button to let the voltage generator to

Find the complex power of the other load. 4. The load shown in figure 1 consists of resistance R in parallel with a capacitor of reactance X. The load is fed from a single-phase supply through a line of impedance 8.4 + j11.2 . The rms voltage at the load terminal is 12000o Vrms‚ and the load is taking 30 kVA at 0.8 power factor leading

(Drug Abuse Resistance Education) teaches our children—from kindergarten through high school—that popularity can be found in positive behavior‚ that belonging need not require them to abandon their values‚ that self-confidence and self-worth come from asserting themselves and resisting destructive temptations. D.A.R.E. teaches them not just that they should refuse drugs and alcohol‚ and not participate in violent activities‚ but how

Introduction This experiment tests electrical conduction. Electrical conduction is the transportation of an electrical charge through a substance. This is done by the electrical charge/current being sent through the substance via electrons. These electrons carry the electrical current/charge throughout the substance’s length until another conductor is able to receive the electrons charge. Part B: Risk Assessment: During the construction of “the modified hurler‚ “

PIPER JEFFREY DEVOLDER Jones Electrical Distribution After several years of rapid growth‚ in the spring of 2007 Jones Electrical Distribution anticipated a further substantial increase in sales. Despite good profits‚ the company had experienced a shortage of cash and had found it necessary to increase its borrowing from Metropolitan Bank—a local onebranch bank—to $250‚000 in 2006. The maximum loan that Metropolitan would make to any one borrower was $250‚000

Electrical Charges: Electrical charges come as plus or minus. Like charges repel‚ unlike charges attract. Electrons and protons have‚ to fantastic accuracy‚ equal and opposite charges. Quarks have 1/3 the electron charge but are never seen alone! In wires electrons do the moving to carry electrical current. In solutions or plasmas there can be positive charge carriers‚ ions or protons. Although the signal to tell electrons to move in wires travels at about 2/3 the speed of light
