I’m sorry, but I am not able to browse the internet and do not have access to specific PDF files. However, I can provide you with some general information about electric potential and capacitance that may be helpful for your study.
Electric potential is a measure of the electric potential energy per unit charge at a particular location in an electric field. It is related to the electric field strength and the distance from the source of the field. The unit of electric potential is the volt (V), which is defined as the work required to move a unit charge from one point to another in an electric field.
Capacitance is the measure of a body’s ability to store an electric charge. It is defined as the ratio of the electric charge on a conductor to the potential difference across it. The unit of capacitance is the farad (F), which is defined as the capacitance of a conductor that stores a charge of one coulomb when the potential difference across it is one volt.
I hope this information is helpful. If you have any specific questions about electric potential or capacitance, please feel free to ask.
