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 ...

Do you understand neutrals and fault current paths? Neutral connections, fault current paths, and grounding considerations can be confusing, but if you understand the basic principles of electricity, ...

A second experiment can be carried out to investigate experimentally how the resistance of a metallic conductor at constant temperature depends on the area of cross section. The above experiment is ...

Plot a graph of resistance, R, in Ω on the y-axis against length, l, in cm on the x-axis. Draw the line of best fit. We can see from the graph that as the length of the wire, l, increases, the ...
