Capacitor Basics: Charge & Discharge Operations

AI Thread Summary
Capacitors store electrical energy and release it when needed, functioning through charge and discharge operations. The charging process involves accumulating electrons on one plate, creating a voltage difference, while discharging allows the stored energy to flow back into the circuit. Understanding these operations is crucial for engineering students, especially in practical applications. Additional resources, such as articles on Wikipedia, can provide further insights into capacitor functionality. Mastering these concepts is essential for a solid foundation in electronics.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Two capacitors, etc.'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
