Question
**Problem Statement:** Assume the *npn* transistor in the circuit below has beta = 100 and VBE(on) = 0.7 volts. If Rc = 5.0 kΩ, what is the collector voltage in volts? **Circuit Diagram:** The circuit diagram consists of the following components: 1. **Power Supply:** - A DC power supply providing +15 V. 2. **Resistors:** - \( R_{B1} = 100 \, \text{k}\Omega \) - \( R_{B2} = 50 \, \text{k}\Omega \) - Collector resistor \( R_c = 5.0 \, \text{k}\Omega \) - \( R_E = 3 \, \text{k}\Omega \) 3. **Transistor:** - An *npn* transistor with three terminals: base, collector, and emitter. **Explanation of Circuit Operation:** - The voltage divider formed by \( R_{B1} \) and \( R_{B2} \) provides the base voltage for the transistor. - \( Rc \) is the load resistor connected to the collector of the transistor. - \( R_E \) is connected to the emitter of the transistor and is grounded. - Based on the given parameters, the transistor’s operation determines the collector voltage. The collector voltage can be calculated using Kirchhoff’s laws and the properties of the transistor. **Objective:** Determine the collector voltage in volts given the values of beta, VBE(on), and the resistances.
