What is internal resistance for a cell.

A collector feedback circuit uses an npn transistor with Vcc= 12V, Rc= 1.2V, RB = 47KΩ. Determine the collector voltage and the collector current if ß = 200.

1) Find the Q-point value
2) Find the minimum power rating of transistor. Given : ß = 50, Vcc = -12V, Rc = 1.8kΩ, R1= 33kΩ, R2 = 5.6kΩ, RE = 560Ω.

What is the minimum value of ß that makes Rin(base) ≥ 10R2 ? Given : Rc = 1.5kΩ, Vcc = 15V, RE = 680kΩ, R1 = 22kΩ, R2 = 4.7kΩ, ẞ = 150.

To what value can RE be reduced without transistor going into saturation. Given : Vcc = 5V, Rc = 1kΩ, RB = 22kΩ, RE = 2.2kΩ, -VEE = -5V.

The base bias circuit is subjected to a temperature variation from 0°C to 70°C. The ß decreases by 50% at 0°C and increases by 75% at 70°C from it's normal value of 110 at 25°C. What are the changes in IC and VCE over the temperature range of 0°C to 70°C Given: RB = 15kΩ, Rc = 100Ω, Vcc = 9V
