Given a common collector amplifier with a collector current of 0.5 mA, with a source resistance of 100 kΩ, calculate the voltage drop across the source resistance and the resulting base voltage.
💡 Hint: Use Ohm's law to find voltage drop.
A common collector amplifier has an upper cutoff frequency of 30 MHz with ideal source resistance. If a source resistance of 100 kΩ is introduced, analyze how this will affect the cutoff frequency.
💡 Hint: Think about how resistance interacts with capacitance.
