The correct answer is: C. High output impedance
An inverter is a device that converts a DC voltage to an AC voltage. It does this by using a transistor to switch a current on and off very quickly. The output voltage of an inverter is determined by the input voltage, the frequency of the switching signal, and the load impedance.
The input impedance of an inverter is typically very low. This is because the transistor is turned on and off very quickly, and there is very little current flowing through the input circuit. The output impedance of an inverter is typically very high. This is because the transistor is turned on and off very quickly, and there is a large voltage difference between the input and output terminals.
The high output impedance of an inverter means that it can be used to drive a large load. However, it also means that the output voltage of the inverter can be affected by changes in the load impedance. This is why it is important to match the load impedance to the output impedance of the inverter.
Here is a brief explanation of each option:
- Option A: Low input impedance. This is not correct because the input impedance of an inverter is typically very low.
- Option B: High input impedance. This is not correct because the input impedance of an inverter is typically very low.
- Option C: High output impedance. This is correct because the output impedance of an inverter is typically very high.
- Option D: High input and output impedance. This is not correct because the input impedance of an inverter is typically very low, while the output impedance of an inverter is typically very high.
