1,/ The coaxial cable can be considered cylindrical capacitor. The radii of the inner and outer cylinders are R₁ =10m and R₁ = 3.10 m. The relative permeability and the critical electric field values are 6, = 2,5 and E 10°V/m. Find a) the capacitance of one meter of such cable and b) the maximum applicable voltage on the cable without the risk of break down. 2,/
