Capacity of the battery - Power & Energy. The power of the battery determines the runtime of a battery. The power/Capacity of the battery is expressed in Watt-hours (Wh). The Watt-hour is calculated by multiplying the battery voltage (V) by the amount of current that a battery can deliver for a certain amount of time.
Advice for this P-Channel MOSFET Power Source Selector
$begingroup$ D2 is the body diode of the MOSFET; you don''t need to add it as a discrete part. Btw that same diode might be important for the proper operation of the circuit at the moment the USB power is removed. It will take some miniscule time for the gate charge to dissipate through R1 (few microseconds probably), but during that time …

Noob design a Power selection circuit with P-Ch Mosfets
VBat is in reality a STANDBY rail of a PSU (Like for the ATX PSU 5V_STB, originally it was a battery but then I''ve changed the specs due to power consumption). The idea is to switch to the proper 5V Rail when the PSU is turned on and increase the power limit on the circuit. The STANDBY power is always present if the device is pluged in.
