WebThe majority current carriers in the PNP transistor are holes. This is in contrast to the NPN transistor where the majority current carriers are electrons. To support this different type of current (hole flow), the bias batteries are reversed for the PNP transistor. A typical bias setup for the PNP transistor is shown in the figure below. WebFeb 1, 2024 · The current flow through the BJT (Ic) is controlled by the size of the base current (Ib). Every BJT has a particular ratio between the size of this 'collector' current and the 'base' current which is called current gain (beta).
