Selection of capacitors. 1. Capacity selection: Large capacitance, the heavier the load, the stronger the ability to absorb current, the larger the capacity of this large capacitance; Small capacitance, based on experience, can generally 104. The experience of others. 1. The capacitance to ground f

Selection of capacitors. When the electrolytic capacitor is in use, if there is no large ripple, the withstand voltage can only be 20% larger than the actual value. That is, the output of 7805 is enough for 6V or 16V, and the output of 7805 is enough for 10V, and there will be no big problem with 1

3. Provides a common formula for constant current charge and discharge:? Vc? T/C. Here's another common formula for capacitive charging: 1-e-t / r / c). In the RC circuit charging formula Vcn (1-e-t / R) is the negative exponential term of e. About the capacitance used for delay how to use the capac

Calculation of charge and discharge time of capacitors. 1. The L and C elements are called “inertial elements”, that is, the current in inductance and the voltage at both ends of capacitors which has certain “electric inertia”. It cannot be changed suddenly. The charge-discharge time is related not
