 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...

 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 ...

 The direction of current flow and electrons has been a very common question. It is the most common but most asked question as well. Many have confusions about the answer, we all know that current is the flow of electrons. So why it always have to be the opposite? Why their direction would be different? Today I will try to get you rid out of this confusion.  First of all, we need to know what is current? An electric current is a stream of charged particles, such as electrons and ions, moving through an electrical circuit or space. It is the flow of a positive electric charge. The strength of current flow in any medium depends on the difference of voltage in that medium. It is measured as the total rate of flow of electric charge through a surface or into a control volume.  And electron flow is what actually happens and electrons flow out of the negative terminal, through the circuit, and into the positive terminal of the source. It won't make any difference as long as the...

 Load shedding is a terrible thing to experience. Especially in summer. But have we ever wondered what causes load shedding? Load shedding is the shutdown of the power distribution system when the capacity of power is less than the demand. Today we will discuss this topic briefly.  Load Shedding Load shedding is an intentional blackout in engineer electrical power shutdown for a time period in different parts of the distribution region. Load shedding depends on the shortage of capacity to meet the demand for electricity. load shedding occurs to avoid a complete blackout of the power system. Blackouts can be localized to a specific part of it can be in the whole country. Sometimes blackouts can happen due to extreme weather. Usually, the blackouts can be caused by insufficient capacity or inadequate infrastructure to deliver power.  The causes of load shedding 1. System loss After producing the power the next part is to distribute it among the consumers. But if the suppli...

 Infinity! a wondering topic to discuss. How can we define an endless, limitless subject. Infinity is a complicated as well as a simple topic. An interesting topic with various topics and logic. Infinity refers to something that is uncountable, unmeasurable, and a thing that is beyond our thinking. We can say that space is infinite. We don't know how big is the universe is. Today we will discuss this weird but interesting topic. So let us get started. Infinity mainly represents the idea of the boundless, limitless thing, that we can't count. But we can just wonder. For example, we can talk about the numbers. The number lines can be infinite. We all know that we can count as far as we want. For the number line, we can discuss its two types which are countable infinity and absolute infinity. 1. Countable Infinity The set of numbers is endless. But we can assign them to each one and still count them. Actually, we can easily count them. If it extends to infinity still we can count...

 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 bul...

 A device fingerprint is usually used for identification. It is one of many other trackings. Device fingerprinting identifies devices based on their specific configuration. Some information is required to create a device fingerprint such as IP address, user agent string, HTTP request headers, installed plugins, list of fonts, client device information (operating system, touch support, language, screen resolution), Silverlight data, timestamp, etc. After collecting the information it creates a user profile and provides personalized ads. How does it work As nowadays tracking and identification is hard and complicated, it's easy to use fingerprints for detecting a specific person. It's more accurate and reliable. People use multiple devices for different types of needs and to seal their identity device fingerprinting is the most useful way. Tech companies use cookies to identify specific customers. But it is not a very reliable way. Cookies can be deleted and information is colle...
