Calculate the base current (IB), collector current (IC), and collector-emitter voltage (V_CE) for a BJT circuit given specific component values.

Here are the calculations for the BJT circuit:

Given values:

• Input voltage $V_B = 5 \text{ V}$
• Base resistor $R_B = 10 \text{ k}\Omega = 10 \times 10^3 \Omega$
• Collector resistor $R_C = 4.9 \text{ k}\Omega = 4.9 \times 10^3 \Omega$
• Collector supply voltage $V_{CC} = 9 \text{ V}$
• Base-emitter voltage $V_{BE} = 0.7 \text{ V}$
• Current gain $\beta = h_{FE} = 100$

i) Calculate $I_B$ (Base current)

Step 1: Apply Kirchhoff's Voltage Law (KVL) to the base-emitter loop.
