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 measures of people’s knowledge, skills and abilities and, therefore, we use tests to help identify people best suited for our jobs.
WHAT IS THE BASIC ELECTRICITY TEST?
The Basic Electricity Test is designed to measure your knowledge and ability to apply concepts, terms, and principles involved in working on or near electrical equipment. Although the test contains some factual questions, it emphasizes your understanding of the subject and your ability to apply what you know, not just your memory of facts or formulas. Although there are no prerequisites for taking the Basic Electricity Test, if you have no prior training or work experience in basic electricity and electronics, you probably will not do well on the test. The Basic Electricity Test consists of 60 multiple-choice questions. Each question has four possible answers to choose from. Some questions refer to figures containing circuit diagrams or other schematics. These will be provided to you. Total testing time is approximately 60 minutes. In some locations, the test is given on a PC using a mouse. A tutorial is provided before the test that provides instructions on how to select answers, move from question to question, and view figures/diagrams. You will have to perform calculations, but you can use a calculator. You may bring a calculator that is silent, handheld, and battery operated. It cannot be solar or have alpha characters on the keypad. The calculator you bring should be able to perform the following functions: Addition, Subtraction, Multiplication, and Division. A scientific calculator can perform these functions. You will use formulas on the test, but you don’t need to have them memorized. A reference screen on the PC contains all the formulas you might need. You can refer to it anytime your memory needs jogging. The scoring of the Basic Electricity Test is based on the number of correct answers. There is no penalty for guessing, so it is to your advantage to try as many questions as possible. If you are unsure about the answer to a question, a careful guess should be made. The Basic Electricity Test covers four main subject areas: • Electricity Fundamentals – Electrical Concepts – Schematic Reading – Circuit Measurements – Circuit Identification • Alternating Current and Reactive Elements • Safety and Protection Devices • Multimeters In addition, you need to know: • Applied Math Page 1 of 16 AT&T PROPRIETARY Rev. 02/08
A brief description of each subject area is provided. If you know and understand these things and can apply what you know, you should do well on the test. ELECTRICITY FUNDAMENTALS Electrical Concepts • Understand basic electrical principles • Understand the laws of attraction and repulsion • Understand the principle of charge • Understand the concepts of current flow, electrical pressure, resistance and energy • Understand the relationship of conductor size and length to current flow and resistance • Identify various electrical units such as voltage, current, resistance and power • Understand electrical static discharge and how it is generated Circuit Measurements • Use Ohm’s law to solve for voltage (E or V), current (I) or resistance (R) • Use the power formula to solve for power (P), voltage (E or V) or current (I) • Understand the relationships of efficiency, power input and power output in a circuit • Calculate the total voltage, resistance and current in simple circuits • Understand the process for simplifying circuits in order to...
