... Note that as gate voltage increases, Ron decreases, which increases the noninverting gain of the U1 op-amp circuit. (You may need to use a smaller value of R1A if your MOSFET has a different Ron vs. VGS characteristic.) Op-amp U2 is configured as an inverting stage with gain = -51. This allows the o ...

Circuit breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
