I‘ve handed in my sheet with all of my working on it so I can‘t refer to it to work these questions out :/ The questions areCalculate the length of a copper wire of cross sectional area 0.8x10^-7 m^2 that has a resistance of 2 ohmsCalculate the resistance between the large faces of a slab of germanium of thickness 1mm and area 1.5cm^2Would someone be able to tell me how to work it out? I‘d really appreciate it :]Thanks
R r x L/A where R resistance, r resistivity, A area of xsection and L length A is given, R is given but r is missing so you cannot find R. Sorry.
