Read the lab before answering these questions.

1. Find the gain for the amplifier in figure 3. The
gain can be determined from these equations: v_{out} = -i_{c} R_{C},
i_{c} = g_{m} v_{be}, and g_{m} = I_{C} / V_{T},with I_{C} = 5 mA.

2. In figure 4 find R_{B} so that I_{C} = 5 mA (assume a beta of 100).
What would V_{O} be?

For this same circuit, how would you find beta if you were given R_{B} and V_{O}?
