You're on a roll — here are the solutions for Problems 10, 11, and 18 based on the provided diagrams. --- Problem 10: Given the information provided in Fig. 4.123, determine: Given: V_CC = 12 \, V, I_C = 2 \, mA, V_C = 7.6 \, V, V_E = 2.4 \, V, = 80. Assume V_BE = 0.7 \, V for a silicon transistor. a) R_C Step 1: Calculate the voltage drop across R_C. V_R_C = V_CC - V_C V_R_C = 12 \, V - 7.6 \, V = 4.4 \, V Step 2: Use Ohm's Law to find R_C. R_C = V_R_CI_C R_C = 4.4 \, V2 × 10^-3 \, A R_C = 2200 \, = 2.2 \, k The collector resistor is 2.2 k. b) R_E Step 1: Calculate the base current I_B. I_B = (I_C)/() I_B = 2 × 10^-3 \, A80 = 25 × 10^-6 \, A = 25 \, Step 2: Calculate the emitter current I_E. I_E = I_C + I_B I_E = (2 × 10^-3 \, A) + (25 × 10^-6 \, A) = 2.025 × 10^-3 \, A = 2.025 \, mA Step 3: Use Ohm's Law to find R_E. R_E = (V_E)/(I_E) R_E = 2.4 \, V2.025 × 10^-3 \, A R_E ≈ 1185.19 \, = 1.185 \, k The emitter resistor is 1.185 k. c) R_B Step 1: Calculate the base voltage V_B. V_B = V_E + V_BE V_B = 2.4 \, V + 0.7 \, V = 3.1 \, V Step 2: Calculate the voltage drop across R_B. V_R_B = V_CC - V_
