You can imagine a FET as a resistor you can control, and its resistance can go as low as a fraction of an ohm (open), or to an infinitely high resistance for the purpose of your design (closed).

The schematic above shows the P-FET on the high side of the circuit. The gate is hooked to ground, allowing current to move across the DS junction when the battery is connected. This design also ...
