Human: What is the difference between a spherical and a cylindrical capacitor? Assistant: 
The main difference between a spherical and a cylindrical capacitor is that a spherical capacitor has a curved surface, while a cylindrical capacitor has a straight surface. A spherical capacitor can be used to store electrical energy in a smaller space than a cylindrical one due to its shape, which allows for higher capacitance values. Additionally, spherical capacitors are more resistant to external forces compared to cylindrical ones, making them better suited for harsh environments such as aerospace applications.
