Question

For a base current of 10 \(\mu\)A, what is the value of collector current in common emitter, if \(\beta = 100\)?

• A. 10 \(\mu\)A
• B. 100 \(\mu\)A
• C. 1 mA
• D. 10 mA

Hint:

Collector current = \(\beta \cdot I_B\) in CE mode. Convert units properly!

Answer 1

The Correct Option is C

Given: \[ I_B = 10\,\mu A = 10 \times 10^{-6}\,A, \beta = 100 \] Step 1: Use transistor relation: \[ I_C = \beta \cdot I_B \] Step 2: Substitute values: \[ I_C = 100 \cdot 10 \times 10^{-6} = 1000 \times 10^{-6} = 1\,\text{mA} \]
