Transistor current gain
β = I_C / I_B; α = I_C / I_E
Where: I_B = I_B, I_C = I_C, β = fringe width (m) / current gain
Solved example
Given: I_B = 7, I_C = 5
Find: beta (fringe width (m) / current gain)
- Formula: β = I_C/I_B
- Substitute the values: β = 5/7
- Result: β = 0.714286
Answer: beta = 0.714286
