Hello and welcome back to another episode of Physics Parted-Done. Today I am going to discuss the Ohms law and its application. Later on we will do a virtual lab about Ohms law. Ohms law is a fundamental concept in electrical and electronics engineering. It states that the current flowing through a conductor is directly proportional to the voltage applied across it. If you want to revise the concept of current and voltage you can watch my video, I will share the link in the description. It states that the current flowing through a conductor is directly proportional to the voltage applied across it. This condition is valid if the temperature and another physical conditions remain constant. The formula for the Ohms law is v is equal to ir, where ir is the current which is measured in emperors, v is the voltage or potential difference measured in volts and r is the resistance measured in ohm. The technical details of Ohms law are crucial for understanding how electricity works in circuit. For example, if you increase the voltage applied to the resistor while keeping its distance constant then the current flowing through it will increase proportionally. Similarly, if you decrease the resistance of the circuit while keeping its voltage constant then more current will flow through it. One of the primary advantages of Ohms law is its simplicity. Understanding Ohms law can help engineers design circuits that operate efficiently and safely. By calculating the expected current flow through various components, engineer can select appropriate resistors and other components to prevent overheating or damage. Without an understanding of Ohms law, electrical system can be dangerous and unreliable. Ohms law formula and technical details are essential concepts for anyone working with electricity or electronics. Understanding this law allows engineers to design safe and efficient circuits that means their intended specification. The simplicity of the law and versatility make it essential tool for designing effective electrical system while also adding in troubleshooting issues that arise within these system. Let us try a virtual lab to understand more about the Ohms law. So you can see the setup of the virtual lab here. We have a power supply here which is providing right now 30 voltages, voltages and volt is the unit of potential difference. As we discussed this Ohms law according to Ohms law voltage and currents are directly proportional and you can see here I have a resistor here which value is right now 500 ohm and I have an emitter which is showing current right now is 60 milliampere. So let us see what happened and what is the effect of voltage if I increase or decrease the voltage what happened to the current. And same time we will also check what happened if we change the value of the resistance. So if I increase the voltage you can see here the current is also going to be increase. You can see the relationship of the voltage and current here when I increase the voltage current is also increase whereas resistance is fixed right now. So on the fixed resistance according to Ohms law when you increase the voltage current will also be increase. Likewise if I decrease the voltage you can notice the current is also going to be decrease. You can look at the graph it shows that directly a proportional graph because it is going to be increase with each other and decrease with each other. Same way if I tried to change the value let me fix again to 30 voltage. So again it is now 30 voltage and 60 milliampere. So what happened if I change the value of resistance. So if when I am going to increase the resistance you might notice that current is going to be decrease. So if the voltage is fixed now and I am increasing the resistance current is going to be decrease. And likewise you can see the change in the graph. So if I decrease the resistance you can see the current is going to be increase. So this is the relationship between voltages and current according to Ohms law V is directly proportional to current. The voltage is directly proportional to current. When V is increase current is also increase when V is decrease current is also decrease. And V is equal to IR is the conclusion of Ohms law. So I think it is enough for today. So thank you very much for listening and watching. I hope you enjoyed the video. I hope this video is useful for you. So take care of yourself and don't hesitate to write an email if you have any question, query, suggestion and even classes are required. Take care of yourself meanwhile. See you in the next video. Goodbye.
