Abstract: The investigation involved testing the factors of pencil lead length‚ cross-sectional area‚ temperature and lead type to find out how they affected pencil resistance. The hypothesis was proven as the length (series circuit) graph was exponential and the area (parallel circuit) graph was that of a power function. Higher clay based pencils (2H) had higher resistance to that of higher graphite based pencils (6B)‚ and temperature did not greatly affect the resistance. The reasons as to why diamond

experiment was performed to determine the transformation of delta to wye networks and wye to delta networks. It is easily to determine the transformation of networks using the formula of delta and wye connection. II. Introduction Standard 3-phase circuits or networks take on two major forms with names that represent the way in which the resistances are connected‚ a wye connected Network which has the symbol of the letter‚ Υ (wye) and a Delta connected Network which has the symbol of a triangle‚ Δ

Electricity Circuit symbols Potential difference The energy which is delivered to an electric circuit comes from the supply. The greater the potential difference of the power supply the more energy is delivered. Potential difference is measured in volts‚ which has the unit symbol V. Cells in series The more chemical cells that are connected in series the greater the potential difference that they supply. The potential difference of a number of cells connected in series is the sum of each

EQUIPMENT IN THIS LAB‚ YOU MIGHT DAMAGE THE EQUIPMENT. ALSO‚ YOU MAY SOMEDAY USE EQUIPMENT THAT COULD INJURE OR KILL YOU IF USED IMPROPERLY. 2 INTRODUCTION AND TEST CIRCUITS. The purpose of this experiment is to learn to use the test equipment‚ in order to do that we need a source of measurements. So we need to build some circuits using resistors and a power supply or the function generator. In this lab we will be measuring voltages (peak-peak‚ avg(DC)‚ rms(AC))‚ current(DC)‚ frequency‚ period
