A barn (symbol: b) is a metric unit of area equal to 10 m (100 fm ). Originally used in nuclear physics for expressing the cross sectional area of nuclei and nuclear reactions, today it is also used in all fields of high-energy physics to express the cross sections of any scattering process, and is best understood as a measure of the probability of interaction between small particles. A barn is approximately the cross-sectional area of a uranium nucleus. The barn is also the unit of area us… WebA cell is connected to a wire of resistivity ρ, and l. The wire has the shape of a truncated cone, which means that its radius varies linearly with distance along the wire.
