Discussion Overview
The discussion revolves around calculating the time it takes for a 22 nF capacitor, initially charged to 10V, to discharge to 90% of its voltage when connected to a 100kΩ resistor. The focus is on the application of the time constant in the context of capacitor discharge.
Discussion Character
- Technical explanation
- Mathematical reasoning
Main Points Raised
- One participant presents the equation v = v₀e^(–t/τ) for capacitor discharge and questions its appropriateness.
- Another participant confirms that the equation is correct and emphasizes the importance of its application.
- A participant calculates the time constant τ as 2.2 ms and derives the time t for the voltage to fall by 10% as approximately 232 µs.
- A subsequent reply agrees with the calculated time, suggesting that the solution is correct.
Areas of Agreement / Disagreement
