Relationship Between Alpha And Beta Current Gains — the NEET Physics formula with its derivation, variables, validity constraints and worked solver.
Relationship between Alpha and Beta Current Gains Applicable to Bipolar Junction Transistors (BJT) operating in the active region to relate current gains of different configurations. Use the relation IE = IB + IC Divide the equation by IC to get IE/IC = IB/IC + 1 Substitute 1/ for IE/IC and 1/ for IB/IC Rearrange the equation 1/ = (1 + )/ to solve for must be less than 1 is typically much greater than 1 Only applies to DC or low-frequency AC current gains Thinking alpha can be greater than 1 Mixing up the formulas for alpha and beta Using the formula for FETs instead of BJTs
