Introduction to Electricity
Electricity is an essential part of our daily lives and a fundamental concept in electrical engineering. Understanding basic electrical concepts can help you appreciate how various devices operate. This blog aims to shed light on these concepts and their practical applications.
What is Voltage, Current, and Resistance?
At the heart of electrical systems are three key principles: voltage, current, and resistance. Voltage, measured in volts, is the force that pushes electrical charges through a circuit. Current, in amperes, denotes the flow of these charges, while resistance, measured in ohms, refers to the opposition to the flow. These three elements are interconnected, described by Ohm’s Law, which states that voltage equals current multiplied by resistance (V = I × R).
AC vs. DC Electricity
Electricity can be categorized into two types: Alternating Current (AC) and Direct Current (DC). AC is the form of electricity that powers most of our homes and appliances. It changes direction periodically, making it suitable for long-distance transmission. In contrast, DC flows in one direction, commonly found in batteries and small electronic devices. Understanding these types can help you choose the right power source for your projects.
