Because students are using it, it needs to be short-circuit-proof – no possibility that a mix-up in control signals can cause the drive to short out the rails (see DANGER, right). BTW, don’t use these ...

The damn thing worked – it showed the schematic symbol for an NPN transistor with Collector, Base, and Emitter connected to Pins 1,2,and 3 respectively. Flipping the pins around and re-testing ...

An NPN transistor is an electronic component used as a switch or amplifier. It has three legs: base (B), collector ©, and emitter (E). In circuit diagrams, the base is usually in the middle, the ...

NPN transistors are key components in electronics, used as switches or amplifiers with three legs: base, collector, and emitter. Thyristors are semiconductor switches with three legs: gate, anode ...
