    Capacitance and max field strength of a concentric sphere capacitor

    Just to clarify - is the maximum electric field just outside the 15cm radius sphere the same as the electric field in the gap between the two spheres?

    Capacitance and max field strength of a concentric sphere capacitor

    Homework Statement A capacitor is formed by two concentric spheres r1= 30 cm and r2=15 cm, with a liquid insulant between them with relative permittivity Er=4. The potential difference between the spheres is 1 kV. Find: 1. capacitance 2. maximum field strength in the gap between the two...
