Question

The value of the voltage controlled current source ia=βva  given β=0.3 and va=9.5mV.

(a) 2.5 mA

(b) 2.85 mA

(c) 1.75 mA

(d) 1.2 mA

I have been asked this question in an online interview.

My query is from Analysis of a Circuit Containing Dependent Sources in division Circuit Variables and Elements of Electric Circuits

Answer 1

Correct choice is (b) 2.85 mA

The explanation is: ia= 0.3*9.5*10^-3=2.85mA.
