Base Bias: A base-biased transistor has a base resistor of 22 kohms, a collector resistor of 100 ohms, a dc beta of 100, a collector-supply voltage of 15 V, and a base-emitter voltage of 0.7 V. What is the collector current? The collector-emitter voltage? Draw the dc load and show the Q point.

Answer: The collector current is 65 mA and the collector-emitter voltage is 8.5 V. The dc load line has a Q point with coordinates of 65 mA and 8.5 V as shown below. Also note the saturation current of 150 mA at the upper end of the dc load.
