Proteus 8 Professional installation guide for free.

How to install proteus 8 professional for a free full guide for installation? Hello friend, I hope you all fine. Don't worry if you have not all electronics components to learn of circuit designing. Today we are going to learn an interesting topic that is a simulation of electronics circuits on your computer. A lot of learner that can't afford for costly rated electronics components to learn. For these learners, this is an easiest way to make a circuit and simulate it on your computer. This is also helpful for professionals, who run their circuits firstly on this software and thereafter they try to make circuits on PCB boards. Yes, this is the software (Name: Proteus 8 professional) on which we will work to design our circuit. This is not free software but I will show you that How to download and install the proteus 8 professionals. Download link of Proteus 8 professional: https://getintopc.com/softwares/electronics/proteus-8-6-professional-free-download/ Step 1: After clic

Use of resistors.

Hello freind I hope you all fine. First of all, we will talk about Ohm's law which is very very important in circuit designing. Ohm's law: V = I × R V = Voltage between any two terminals in the circuit. I = The electric current flowing through these two terminals. R = Equivalent resistor between these two terminals. Example 1. How to control the speed of dc motor using a resistor or potentiometer. Note: Always remember that Ohm's law is valid for both AC and DC sources. First, let's we take figure 1 for an explanation. As you can see in above figure 1 that a dc motor is connected to a 12V dc battery. An ammeter is connected in a series of motor and the current is 0.50A passing through the motor. Now the question is which value of the resistor and which power rating of the resistor should I use to control the dc motor. How to define it. (i) The

What is resistor?

Hello friends this is my first blog. In this blog, I am going to show what is a resistor and I explain in brief how you can use a resistor in practical circuit making. I know that you all know much about resistor so I will focus mainly on practical use. What is a resistor? As you can see resistor and its symbol in the above picture. The resistor is an electronic device that controls the amount of electric current passing through it. Its means if you want to give a certain current (ie. 300mA) to load then you can do it simply inserting a resistor of a specific value ( specific means: a certain value of the resistor depends on the value of current which you want to flow or give your load) between that branch by which current go to the load. From the above paragraph, we can simply say: Resistor is a current limiting device that controls the current passing through it. Note: The "resistor" is an electronics device (component) but "
