Understanding Relays: Types and Working Principles A relay is an electromechanical or electronic switch that allows a low-power signal to control a high-power circuit. It plays a crucial role in automation, protection, and signal switching across various industries including automotive, industrial control, home appliances, and telecommunications. 🧠 What is a Relay? A relay is an … Read more
1. What is Ohm’s Law? Answer:Ohm’s Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R).V=I×RV = I \times RV=I×R Where: VVV = Voltage (Volts) III = Current (Amperes) RRR = Resistance (Ohms) 2. … Read more
What is a Solar Power Efficiency? Definition: Solar power efficiency refers to the ratio of the electrical energy produced by a solar panel or system to the amount of sunlight energy that hits the panel’s surface. It is expressed as a percentage and indicates how effectively the panel converts sunlight into usable electricity. Higher efficiency … Read more
What is Electrical Energy Efficiency? Definition: Electrical energy efficiency refers to the ratio of useful output of an electrical system to the input energy supplied to it. It is a measure of how effectively electrical energy is converted into the desired output, whether that output is mechanical work, heat, light, or other forms of useful … Read more
Duke Energy Power Company History: Duke Energy, one of the largest electric power holding companies in the United States, has a rich history that spans over a century. Here’s an overview of its history: Early Beginnings (1900s) 1904: Dr. Walker Gill Wylie and James Buchanan Duke founded the Southern Power Company to provide electricity for … Read more
What is a Volt Ampere? Definition: A Volt-Ampere (VA) is a unit of measurement for apparent power in an electrical circuit. It represents the product of the root-mean-square (RMS) voltage and the RMS current in the circuit. Apparent power combines both real power (which performs actual work and is measured in watts) and reactive power … Read more
What is a Watt Hour? Definition: A watt-hour (Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. It is commonly used to measure electrical energy consumption. Here’s a breakdown of the concept: Watt (W): A unit of power that measures the rate … Read more
