C is the capacitance of the capacitor in farads (F).t is the charging time in seconds (s). e is the base of the natural logarithm. 顺便提醒一下:自举电阻的作用主要是防止首次对自举电容充电时电流太大的限流,英飞凌的驱动芯片一般已经把自举二极管和电阻内置,不需要额外考虑...
A capacitor is connected across an AC generator whose frequency is 47 Hz and has a peak voltage 148 V. The rms current in the circuit is 50 A. a) What is the capacitance of the capacitor? b) What is the magnitude of the maximum charge on one plate of the ...

Calculating voltages and electrical energy becomes much more difficult with a larger system of charges. Voltage also helps untangle measurements like the capacitance of a capacitor or the total energy of a system, not just the potential of a point charge. ...
Rearranging the equation, we can find the external load capacitor value:CX1 = 2(CL - Cstray) For example, if the crystal load capacitance is 15pF, and assuming Cstray=2pF, then:CX1 = CX2 = 2(15pF - 2pF) = 26pF It is difficult to know exactly what the stray capacitan...
