Electrical Engineering Questions and Answers

Basic Electrical Engineering Concepts

1. What is the difference between KVA and KW?
Kilovolt-amperes (KVA) and kilowatts (KW) are two units used to measure electrical power. KVA includes both the real and reactive power, while KW only measures the real power. Understanding the difference is crucial for electrical engineers to design efficient electrical systems.

2. What is the difference between AC and DC current and voltage?
Alternating Current (AC) and Direct Current (DC) are two types of electrical current. AC changes direction many times per second, while DC flows in one direction. AC is commonly used in power distribution systems because it can be easily transformed to different voltages, whereas DC is often used in electronics and specific applications.
