This article explains how to extend the battery lifetime of a device by adding a nanopower converter to an existing system, ...

so the voltage across the resistor is \((9 - 2) = 7 V\) The current is the same through components in series, so the current in the resistor is 12.5 \(mA (0.0125 A)\).

This design also uses a clamping diode to keep the gate voltage within a safe range. But there are P-FETs out there that wouldn’t need that diode or resistor. This method wastes ten times less ...

the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in series, the total voltage (or potential ...
