A coaxial cylindrical cable has an inner conductor of radius a = 0.0058 m, a surrounding conductor of radius b = 0.015 m, and length l = 6.8 m.
a. What is the formula of the capacitance of coaxial cylinders? (see image attached)
b. Calculate the numerical value of the capacitance in F.
c. Express the capacitance C through potential difference across the capacitor ΔV and charge Q.
d. If the potential difference ΔV = 0.3 V, how much charge is stored in the capacitor?
a)
Let We have a coaxial cylindrical cable that has an inner conductor of radius a and outer conductor has radius b and the length is l. and two cylinders are connected by the battery with the potential difference between them is V, and the charge per unit length on the inner cylinder is + and on the outer cylinder is.
Therefore the capacitance of the coaxial cylinder is
