What is power factor? Power factor formula

 What is power factor? Power factor formula In the study of electronics engineering, we often hear the term power factor. It plays an important role in understanding the efficiency of electrical circuits. Let us understand power factor in simple language in this blog post and also learn its formula. What is Power Factor? In simple words, power factor is the ratio of that part of the total current drawn by an electric circuit that is actually used to do useful work. We express it in percentage (%). High Power Factor: This is an ideal situation, where most of the current is used to do the actual work. It is considered to be between 90% to 100%. High power factor is an indicator of efficiency, which means less energy is wasted. Low Power Factor: This means that a large part of the current is being spent in generating reactive power in the circuit instead of doing actual work. This is a power factor of less than 80% and indicates inefficiency, leading to more energy being wasted. Power...

Boost Your Confidence: 10 Essential Questions and Answers for Electronics Engineer Interviews

1. Explain the relationship between voltage, current, and resistance using Ohm's Law. Answer:  Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) applied across it and inversely proportional to its resistance (R). This can be expressed mathematically as I = V / R. Understanding Ohm's Law is fundamental to analyzing and designing electronic circuits. 2. Differentiate between conductors, insulators, and semiconductors. Answer: Conductors:  Materials that readily allow electric current to flow through them due to loosely bound electrons. Examples include metals like copper and aluminum. Insulators:  Materials that strongly resist electric current flow due to tightly bound electrons. Examples include rubber, plastic, and glass. Semiconductors:  Materials with conductivity that falls between conductors and insulators. Their conductivity can be controlled by applying voltage or doping with impurities, making them c...
