2 cards from this section. Quick, good the night before a test.
What is the function of a current amplifier?
Think about the relationship between input and output current.
What does a DC blocking capacitor do?
Consider why we want to isolate AC signals in measurements.
What is the primary function of a current amplifier?
Recall the main role of current amplifiers.
True or False: DC blocking capacitors allow DC current to pass through.
Think about their role in preventing DC interference.
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?
Remember to apply Ohm's law for circuit analysis with the load included.
Design a simple current amplifier circuit. Sketch the circuit and label key components including the blocking capacitor and any resistive loads.
Draw the components carefully, identifying their roles in the system.
