AC Power Advantages And Disadvantages

CHAPTER 1

INTRODUCTION

BACKGROUND OF STUDY

In this world, there are only two main form of electrical power which are direct current (DC) and alternating current (AC). DC power is a power with a constant voltage where the current can only flows in one direction. On the other hand, AC power involve sinusoidal voltage source which the current can flows periodically or alternates. The problem here is that, most of the electronic gadgets operate using AC power but their source or supply for example, battery, where it produce DC power. Besides that, mobility is one of the issues with the improvement of the technology since society should not be restricted to use their electronic gadgets due to limitation of power supply. This is where, power

They both come with their own advantages and disadvantages. DC power produce constant current as it applied from a circuit, a steady constant voltage. As we know, battery is the most mutual source for DC as the characteristic of DC power is the direction of current flow is unidirectional. Today, most of electronic devices operate using DC power as this kind of power has the ability to offer constant voltage in whatever rating the devices run off either high or low constant voltage. Back then, Thomas Edison was the first ever person to transmitted electricity over the city using DC power line. However, there is no transformer at that time, so the supplied voltage is very low and it can only transmitted power for short distance due to instability

Hence, AC to DC converter or DC to AC inverter is a vital in order for the electrical power to change it behavior. This device will allow offer society a freedom in transferring electrical power in either way. Without this device, society will be limited to use their electronic devices as it will only operate by depending to the power source
