PPE hierarchy of control involves prioritizing control measures to protect workers from hazards.
Elimination - Remove the hazard completely (e.g. using automated equipment instead of manual handling)
Substitution - Replace the hazard with something less hazardous (e.g. using non-toxic chemicals instead of toxic ones)
Engineering controls - Isolate workers from the hazard (e.g. installing ventilation systems)

BJT is a current-controlled device while FET is a voltage-controlled device
BJT has two PN junctions (emitter-base and base-collector) while FET has a gate terminal
BJT has higher gain and faster switching speed compared to FET
Examples: Common BJT types include NPN and PNP tr...
A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of transistor used for amplifying or switching electronic signals.
MOSFETs are commonly used in digital and analog circuits for various applications.
They have three terminals: gate, source, and drain.
MOSFETs are known for their high input impedance and low output impedance.
They can be either enhancement-mode (normally off) or depletion-mode (normally...
