【Abstract】 Partial voltage method is used to obtain the changes curve of the voltage on both sides of the capacitor discharging with a double passages digital oscilloscope.The changes curve of the current in the main loop is obtained by the differential of the partial voltage.We can get the pulse current by rating the curve of main loop with our theory inference.更多还原
