Anatomy and supply. The adductors of the hip are part of the inner hip musculature and range from the lower pelvic bone to the femur and knee region. Thereby it lies in between the extensor and flexor group of the thigh muscles. The hip adductors shape the surface anatomy of the medial thigh.
ã»The input capacitor CIN is important to compensate for input currents that are drawn in due to momentary input power shutoffs and switching. ã»A snubber circuit is fundamentally essential to protect switching transistors from surges that occur at the input.
In an NPN transistor, current flows from the collector to the emitter. In a PNP transistor, current flows from the emitter to the collector. How they turn on and off is also different. An NPN transistor is powered on when a sufficient current is supplied to the base of the transistor. Therefore, the base of an NPN transistor must be connected to positive voltage for current to flow in.
