This model shows a transistor amplifier connected to a tuned circuit. Altering the frequency of the signal generator shows that the amplifier gives its best response for an input with a specific frequency, the resonant frequency. The effect on the resonant frequency of altering the value of the capacitor or inductor can also be investigated.

This item teaches:

• about transistors
• about capacitors
• about simple transistor amplifiers
• about the resonant frequency in a tuned circuit
• the effect of altering the value of a capacitor or inductor on the resonant frequency in a tuned amplifier
