23.6.1. Voltage Dependent Current Sources

Try these first

1. 1.

   What is the function of a current amplifier?

   Hint

   Think about the relationship between input and output current.

2. 2.

   What does a DC blocking capacitor do?

   Hint

   Consider why we want to isolate AC signals in measurements.

3. 3.

   What is the primary function of a current amplifier?

   • To amplify voltage signals
   • To amplify current signals
   • To convert power

   Hint

   Recall the main role of current amplifiers.

4. 4.

   True or False: DC blocking capacitors allow DC current to pass through.

   • True
   • False

   Hint

   Think about their role in preventing DC interference.

5. 5.

   Given a current amplifier with an unloaded gain of 10 and an input current of 2 mA, calculate the output current. What if a load with a resistance of 1kΩ is added?

   Hint

   Remember to apply Ohm's law for circuit analysis with the load included.

6. 6.

   Design a simple current amplifier circuit. Sketch the circuit and label key components including the blocking capacitor and any resistive loads.

   Hint

   Draw the components carefully, identifying their roles in the system.
