if i just measure the resistance btw L and N , the resistance should be zero right, then how can it be 0.3 ohms ?

A circuit is a closed loop or pathway through which electricity can flow. It is made up of various components, such as wires, resistors, capacitors, and switches, that work together to control the flow of electricity.
Circuits can be complex and require knowledge of electrical principles and components. It is common to seek help when designing or troubleshooting a circuit.
Ohm's Law is a fundamental law of electricity that states the relationship between voltage, current, and resistance in a circuit. It states that the current through a conductor is directly proportional to the voltage and inversely proportional to the resistance. This law is important in understanding and designing circuits.
Troubleshooting a circuit involves identifying and fixing any issues that may be preventing it from functioning properly. This can include checking for loose connections, damaged components, and incorrect wiring. Having a basic understanding of circuit components and using tools such as a multimeter can make troubleshooting easier.
Yes, it is important to always follow safety precautions when working with circuits. This includes wearing protective gear, such as gloves and goggles, and ensuring the circuit is not connected to a power source while being worked on. It is also important to have a thorough understanding of electrical safety and to never work on circuits alone.
