In a npn transistor the current carriers are
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. WebIt is highly temperature-dependent because it depends upon a number of minority charge carriers that are thermally generated and in turn depend upon temperature. The main source of the leakage current in a transistor is thermally generated minority carrier. consider common emitter configuration.
