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

ELECTRICAL SUBSTATION A substation is a part of an electrical generation‚transmission and distribution system. Substations transform voltage from high to low‚ or the reverse‚ or perform any of several other important functions. Electric power may flow through several substations between generating plant and consumer‚ and its voltage may change in several steps. Substations may be owned and operated by a transmission or generation electrical utility‚ or may be owned by a large industrial or commercial

What is an infinite loop? Write the code for an infinite loop. An infinite loop is a sequence of instructions in a computer program which loops endlessly. Example of an infinite loop: Set k = 1 While k < = 5 Display k End While 7. A FOR loop looks like what other loop in a flowchart? A For loop looks like a count-controlled loop. 8. Why is it critical that accumulator variables are properly initialized? An accumulator is used to keep a running total of numbers. In a loop‚ a value is usually

Phase Locked Loop: The phase-lock-loop (PLL) is commonly used in microprocessors to generate a clock at high frequency (Fout=2GHz for example) from an external clock at low frequency (Fref = 100MHz for example). The PLL is also used as a clock recovery circuit to generate a clock signal from a series of bits transmitted in serial without synchronization clock (Figure below). The PLL may also be found in frequency demodulation circuits‚ to transform a frequency varying waveform into a voltage.

1. It’s easy to get your first job Electrical engineering students fairly easy find their first job because most employers in electrical field search for fresh mind‚ with fresh knowledge and at the same time they get young people they can mold to their own specific needs and make experts out of them. 2. You can work in another country Working as electrical engineer opens you lots of opportunities in other countries. Laws of math‚ electricity and physics are universal and your gained knowledge

Communication Electronics Unlocked Acquisition Tracking(locked) ABSTRACT We were assigned to build a phase locked loop frequency synthesiser. The purpose is to help students to gain experience in hardware construction‚ coordinated teamwork and project management. The design uses 74HC4046‚ a PLL integrated circuit (IC) made from CMOS technology A PLL is a closed loop frequency system that locks the phase of an output signal to an input reference signal. The term “lock” refers to a constant
