Me: Electronic device is divided into 2. . One is online deivce. . One is offline device. If a device is offline, no choice but, the direct current is from the power supplier.
.
Me: If the device is online, the direct current can be from the network provider or from the power supplier. .It depends on the timing. . 

John: Capacitor 0 and Capacitor 1 are public capacitors. . They don't belong to power supplier. . Nor do they belong to network supplier. . 
.
Me: If capacitor 0 discharge, the current flow to the right side, direct current is from the network provider.
.
If (capacitor 0 = discharge)
{
current_from = network supplier

}
else if (capacitor 1 = discharge)
{
current_from = power supplier
}
