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?

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...
