Lesson: Capacitance & Capacitors
Solve the problem:
The two metal objects in the figure below have net charges of +70 pC and -70 pC, which result in a 20 V potential difference between them. (a) What is the capacitance of the system? (b) if the charges are changed to +200 pC and -200pC, what does capacitance become? (c) What does the potential difference become?
Given:
(a) What is the capacitance of the system?
(b) if the charges are changed to +200 pC and -200pC, what does capacitance become?
(c) What does the potential difference become?
