What are the Common Misconceptions About Electricity

 Electricity is a very common term in our daily life. Our regular activities largely depend on electricity. As we are dependent on technology it's a must to have electricity in the first place. Home, schools, factories all depend on electricity. In summer it's impossible to stay without electricity. but regarding this common term, we all have some misconceptions. From the general people to engineering students a huge portion of people holds these misconceptions. Today I will discuss some common misconceptions about electricity and its solution. So let's check it out.



1. High resistance bulbs are brighter than low resistance bulbs

Some think that the more resistance a bulb has the more it will transfer the energy. But it is a full misconception. This thinking comes from, resistance which is an obstacle for current to flow, so the more current tries to get through, the more electricity passes through the wire. but the resistance has nothing to do about the brightness of a bulb. If the resistance is thee maybe less electricity but the brightness will be always the same. And if the resistance is too high the current flow will be zero and no energy will be transferred. 

2. Charges move very quickly through empty wires.

People think that in empty wires there is no resistance to the current flow will be very easy and quick. But in wires, there are already full of free electrons and they move very slow and at the same time. The wires have resistance where the electrons speed up. In the flow the faster moving electrons meet with lattice and energy can be transferred through resistance in the wire. 

3. The current takes the easiest path

This topic is discussed in the short and parallel circuits where there is different resistance. It is a very common misconception among people. It is not the current who changes roue. If the circuit is changed the current flow will automatically be changed according to the circuit. If the circuit is changed then the current is changed.

4. Electric shocks are common to mammals 

We always see that birds are not electrified when they sit on electric wire. So the thinking automatically comes that electric shocks are only applicable for mammals. But it is not completely true. If an animal can complete a circuit then the electricity will flow in them and they will get an electric shock. 

5. When the switch is off there is no electricity

This is a very common misconception. After we turn off the switch there is still electric energy. That's why we see light for a few seconds in the bulb after turning off the switch. Because for a few moments the energy can be stored.

5 Ways How Artificial Intelligence Will Impact Our Future

In the world of technology AI is on the tip of everyone's tongue these days. AI being a major trend in tech development for a while, AI appearing more and more like one of the most demands in areas of expertise. Artificial intelligence is the simulation of human intelligence processes by machines, especially computer systems. Specific applications of AI include expert systems, natural language processing, speech recognition, and machine vision. Most artificial intelligence systems have the ability to learn, which allows improving their performance over time. The recent research on AI tools, including machine learning, deep learning, and predictive analysis intended toward increasing the planning, learning, reasoning, thinking, and action-taking ability. As AI is becoming part of our life, it will affect our future nearly. Here I am showing some of the scenarios that can be happen in near future: Transportation: Although it could take a decade or more to happen, autonomous cars will...

Why Stones Used in Substation?

The substation is combined with many electrical devices like transformers, isolators, electric lines, etc. Electrical devices are sensitive and have to protect carefully. Usually, the protector of the substation is stone. Isn't it surprising? Have you thought it should be more advanced? In the world of technology why stone is used as a protector? You will be surprised to know the fact that stone is the perfect natural protector. Today I will explain this topic to you. The most important part is the ground potential rise (GPR)  The maximum electrical potential that a substation grounding grid may attain relative to a distant grounding point assumed to be at the potential of remote earth. This voltage GPR is equal to the maximum greed current times the grid resistance. Step voltage: It is defined as the maximum potential difference that exists between the feet when a fault current flows in the body. A particular case of step voltage is the transferred voltage where a voltage is trans...

What is mAh Mean in a Battery

 We all use batteries, right? But how many of us know how the battery actually works? We don't have to know about the complicated terms of chemistry formula but basic things like mah are worth learning about. mah is a basic topic of battery. It explains the capacity, the time, we can use a battery from mah. I will try to explain easily about mah. So let's get started. The capacity of batteries is indicated as mah. Mah capacity rating explains the storage capacity available for a particular battery. An ampere-hour is a unit of electric charge. Normal batteries, such as those in mobile phones and digital cameras, are often rated in milliampere-hours. The milliampere-hour is one-thousandth of an ampere-hour and is a technical term for how much electrical charge a particular battery will hold. As an example, using higher mah batteries in a device with constant electrical consumption will theoretically give longer operating times. A battery with a capacity rating of 1000 mah could d...
