As we very frequently encounter with these terminologies when we go through the basic electrical circuit concept, so let’s understand definition one by one- Resistance(R) Resistance is a material property which opposes the flow of current to some extent in a material. When we apply a potential difference across the conductor then it encourages the … Read more
