Electric Potential, Energy and...
Objectives
|
Upon completion of this chapter, you should be able to:
- understand the concept of electric potential difference ('voltage') and its relationship to electric potential energy and calculate electric potential differences and electric potential energy.
- explain what is meant by an equipotential surface, sketch equipotential surfaces for simple charge configurations, and explain the relationship between equipotential surfaces and electric fields.
- define capacitance and explain what it means physically, calculate the charge, voltage, electric field, and energy storage for parallel-plate capacitors.
- understand what a dielectric is and understand how it affects the physical properties of a capacitor.
- find the equivalent capacitance of capacitors connected in series and in parallel, calculate the charges, voltages, and energy storage of individual capacitors in series and parallel configurations, and analyze capacitor networks that include both series and parallel arrangements.
