Created by StemPy LabA student builds a pre-amplifier for a small sensor with one transistor of current gain . The load in the collector lead is , and she measures an input resistance of at the base. By what factor does the circuit multiply a small signal voltage? Give the size only.
← All Quizzes
← A transistor works as a switch with the load in the collector lead. A student applies a high voltage to the base through a resistor, so that the base current is more than the least current for saturation. What does she find at the output, taken across the transistor from the collector to the emitter?The two inputs of a NOR gate are joined together, and one signal A is applied to both. A student writes the truth table of the output for A = 0 and for A = 1. Which behaviour does she find? →
