Question
**Problem E1**

a. Design component \( R_{CS} \) for load current of 5 mA. Assume \( V_{BE} = 0.7 \, \text{V} \).

b. If a specification is given that \( V_{CE} \) must remain > 1V, can the load current of 5 mA be provided to a 2.5k load? How about a 2k load?

c. Determine the range of loads that meet the specification above.

**Circuit Diagram:**

- The circuit includes a transistor \( Q_1 \) with:
  - \( R_B1 \) and \( R_B2 \) resistors connected to the base.
  - \( R_{CS} \) connected between the emitter and ground.
  - \( V_{CC} \) is the power supply voltage.
  - \( R_{LOAD} \) is depicted, with the load current \( I_{LOAD} \) flowing through it.

**Values Given:**

- \( R_{B1}, R_{B2} = \text{1k Potentiometer} \)
- \( R_{B1} = 800 \, \Omega \)
- \( V_{CC} = 12 \, \text{V} \)
