How to calculate equivalent capacitance to a battery?
I have a 1.25V 2Ah battery and I''m trying to calculate a equivalent capacitance with rated voltage of 2.7V for each of those batteries. This is what I did: Work of Battery = $1.25V cdot 2A cdot $begingroup$ Olin is pedantically addressing the way you have used a high degree of precision in your calculation when it was not essential to …
8.2: Capacitance and Capacitors
Determine the rate of change of voltage across the capacitor in the circuit of Figure 8.2.15 . Also determine the capacitor''s voltage 10 milliseconds after power is switched on. Figure 8.2.15 : Circuit …
Measuring Capacitors
Remember, if the ESR impacts the time a capacitor can charge and discharge in, then it affects the maximum frequency that capacitor can be used at. This is because the higher the frequency, the shorter the time available for a charge/discharge cycle to take place in. ... The only other thing needed is a multimeter to measure the voltage, and ...
