3- 1.5 volt batteries with casing 3- jumper wires with crocodile clips Multimeter Scissors Infrared Thermometer 1 roll of insulation tape Procedure 1. Wind the wire around the PVC pipe. Fix the ends of the wires to the insulation tape. Remove about 3 cm. of insulation from the wire using the tips of the paper knife. Measure the resistance of the wire using the ohm setting on the multimeter. 2. Connect the batteries in series using the jumper wires to produce 4.5

BASIC ELECTRICITY TEST TEST INFORMATION PAMPHLET WHY DO AT&T AND ITS AFFILIATES TEST? When individuals are being considered for our available job openings‚ they go through a selection process to measure their knowledge‚ skills and abilities to determine if they can perform the jobs in a satisfactory manner. It is to the advantage of both you‚ as a job candidate‚ and the company that only those who can perform at acceptable levels be placed on the job. Research has shown that tests provide accurate

Which Fruit or Vegetable Generates the Most Electricity? Abstract People always talk about saving energy‚ or becoming “eco-friendly”. People have found many ways to produce electricity‚ but have they ever tried fruits or vegetables? This project finds which fruit or vegetable produces the most electricity. I tested ten different fruits and vegetables (independent variable) to see which generated the most electricity by measuring the amount of electricity produced in mV (dependent variable)

8 Cross over cable is used to connect two similar devices e.g 2 computers. The straight cable is used to connect two dissimilar devices e.g computer and switch. Exercise 4.1.9 S1 and S2 will require a crossover cable. Exercise 4.1.10 A multimeter or a multitester‚ also known as a VOM (Volt-Ohm meter)‚ is an electronic measuring instrument that

Case Study: Does the Sun’s Angle Affect the Output Of a Solar Cell? Abstract During the experiment to determine Solar Cell Energy‚ one unit of flexible solar cells was exposed to solar radiation at different angles in one axis of rotation. The cells were attached to a adjustable plane with a protractor that acted like a “see-saw” to adjust the angle of the solar cells to the Sun. Around the plane‚ a column of cardboard was constructed with black fabric covering the inside

The following is a project made by anonymous: INTRODUCTION The general purpose photoconductive cell is also known as LDR – light dependent resistor. It is a type of semiconductor and its conductivity changes with proportional change in the intensity of light. There are two common types of materials used to manufacture the photoconductive cells. They are Cadmium Sulphide (CdS) and Cadmium Selenide (CdSe). Extrinsic devices have impurities added‚ which have a ground state energy closer to the conduction

Accountability and the Importance of Taking Care of Your Equipment "Accountability" stems from late Latin accomptare‚ meaning to account. Accountability in the military is the obligation imposed by law or lawful order or regulation on an officer or other person for keeping accurate record of property‚ documents‚ or funds. The person having this obligation may or may not have actual possession of the property‚ documents‚ or funds. Accountability is concerned primarily with records‚ while responsibility
