Capacitor Discharge: Impact of Capacitance on Discharge Intensity

Click For Summary
Capacitance significantly affects the discharge characteristics of a capacitor. A larger capacitor will discharge more charge over a longer period compared to a smaller capacitor at the same voltage and resistance load. Although the initial current may be the same for both capacitors, the larger capacitor contains more stored energy. The term "intensity" is deemed non-specific in this context. Understanding the relationship between capacitance, charge, and voltage is crucial for analyzing discharge behavior.

capacitor capacitance
I don't know if the capacitance of a capacitor is large, the capacitor will discharge with greater intensity than other capacitors with the same voltage but smaller capacitance, right? Thanks

Intensity is not a meaningful term.

Assuming the same initial voltage, a large capacitor will take longer to discharge than a small capacitor, with the same resistance load. The initial current will be the same, but there is more charge in the bigger capacitor. C = Q / V.
 
Hello! I want to generate an RF magnetic field at variable frequencies (from 1 to 20 MHz) using this amplifier: https://www.minicircuits.com/WebStore/dashboard.html?model=LZY-22%2B, by passing current through a loop of current (assume the inductive resistance is negligible). How should I proceed in practice? Can i directly connect the loop to the RF amplifier? Should I add a 50 Ohm in series? Thank you!
