2016 Phase II 1 question

1. 1 Semiconductor Electronics Easy
   For CE transistor amplifier, the audio signal voltage across the collector resistance of 2 k$\Omega$ is 4 V. If the current amplification factor of the transistor is 100 and the base resistance is 1 k$\Omega$, then the input signal voltage is:
   A 30 mV B 15 mV C 10 mV D 20 mV
