Hi all,
Please can you help me because i am in the first steps and i have difficult.
Why resistors used to resist the current flow in electrical circuits?
I you do not apply resistors, you have a high change that too much current to damage the components. I advice to study ohm’s law. There are many articles on the internet, but one to start simple : https://www.toppr.com/guides/physics/el … esistance/
paulvha is correct! Resistors physically resist the incoming current, making them a kind of gatekeeper. That energy has to go somewhere and is usually in the form of heat. That’s how sometimes too much current will burn them out and release smoke. For more information you can also check out our tutorials and learning resources:
