Electrical apparatus used for switching electrical circuits

Search Results for: Electrical apparatus used for switching electrical circuits

as an electronic switch, in grounded-emitter configuration. transistors are commonly used in digital circuits as electronic switches which can be either in an "on" or "off" state, both for high-power applications such as switched-mode power supplies and for low-power applications such as logic gates

with greater energy efficiency are usually possible. for low-power applications (for example, voltage amplification) in particular, energy consumption can be very much less than for tubes. complementary devices available, providing design flexibility including complementary-symmetry circuits, not possible...
