In the circuit shown in figure when the input voltage of the base resistance is 10 V . Find the values of `I_b , I_c and beta` .

Answer

A, B, C

Explanation

Given circuit is equivalent to
` (##DCP_V05_C35_E01_025_S01.png" width="80%">
In base emitter loop ,
` V_B = I_B R_B `
` rArr I_B = V_B / R_B = 10 / (400 xx 10^(3))`
` = 25 xx 10^(-6) A `
` = 25 mu A `
In emitter - collector loop,
` V_C = I_C R_C `
` rArr I_C = 10 / (3 xx 10^(3)) `
` and ` beta_DC = I_C / I_B = (3.33 mA) / (25 mu A) `
` = 133`
