Weba silly thing to do but the diodes are not the same. When current flows through one diode. it provides carriers to carry current through the other part of the element. Thus, in its most. basic form, a transistor is a current amplifier. Bipolar transistors come in two basic types: npn and pnp. The current flow in a npn. WebMar 11, 2024 · For an NPN transistor, it consists of a layer of P-doped semiconductor between two layers of N-doped material, where electrons are passed from the emitter to the collector instead. The emitter then “emits” electrons into the base, with the base controlling the no. of electrons the emitter emits.
