A common collector amplifier setup shows V_dd = 12V, R_E = 1kΩ, and target I_B = 20µA. Calculate the resultant I_C using β = 150.
💡 Hint: Apply the beta relationship for current in a transistor.
Consider an amplifier with R_C = 1kΩ. If the collector current (I_C) is determined as 2mA, find the voltage drop across R_C.
💡 Hint: Recall Ohm's Law to establish the voltage drop calculation.
