1. INTRODUCTION 1. OVERVIEW In order to achieve several small scale and large scale objectives in various electronic circuits‚ it is highly essential to regulate the voltage supply‚ given to electronic circuits. This project‚ namely VARIABLE VOLTAGE REGULATOR‚ aims at fulfilling such small goals‚ using the 3-terminal voltage regulator LM317. The circuit consists of an IC LM317 and a set of resistors and capacitors‚ in addition to the transformer and the rectifying element. The AC

Activity 2: Cultural Variables in Communication Dimensions of national cultures Power distance index (PDI): "Power distance is the extent to which the less powerful members of organizations and institutions (like the family) accept and expect that power is distributed unequally." Cultures that endorse low power distance expect and accept power relations that are more consultative or democratic.
