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.

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...

How does Transistor Work

 The transistor is a semiconductor device for amplifying, controlling, and generating electrical signals. Transistors are the active components of integrated circuits that containing billions of minuscule devices etched into the surface. It is used as an amplifier or switches electronic signals and electrical power. Transistors are one of the basic building blocks of modern electronics. the word transistor is made of the two words, transfer and resistance. This is because it has the function of transferring the resistance from one end of the device to the other end or we can say, transfer of resistance. Transistors have very high input resistance and very low output resistance.  It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. It works when the holes start moving across the two junctions between the n-type and p-type silicon. When turning a small input current into a large output current, the transistor acts ...

What Does It Mean By Dny11 in Transformer?

We often see transformers in our way almost every day, everywhere. We all might have noticed that there is something written in the transformer like Dny11. But we don't know what does it mean? We can guess that the numbers on the transformer windings show the turns ratio between windings. But by reading this article we might confirm this guess.  The first letter D shows that the primary winding configuration is in delta connection. The second small letter n shows that it has the neutral point and the small y shows that it is star connected. Letter 11 shows the phase difference between the primary and secondary connection according to clock configuration. When the clock hands are between 11 and 12 the angle between them is 30 degrees. So, Dny11 means  D- Primary winding in delta connection ny-Secondary winding in star connection with a neutral point 11- There is a phase angle difference of 30 degrees between the primary and secondary line voltages. The secondary line voltage la...
