The hindrance to the flow of electric charge is known as Resistance. The obstruction posed in the way of current carrying particles by fixed particles creates resistance in an electric circuit. Since ...

Across the entire sphere of electronics and electrical engineering, there aren’t many principles that are as fundamental as Ohm’s Law.  Named after the ...

The control variables are kept the same by: not changing the wire during the experiment (material, length and cross section area of the wire stay the same); keeping the current small (temperature of ...
