Quizplus · Accepted Answer

This configuration, where the emitters of an npn and a pnp transistor are connected to each other and to the load, is characteristic of a Class B amplifier. Class B amplifiers use two complementary transistors, one conducting for the positive half-cycle of the waveform and the other for the negative half-cycle, to improve efficiency.
