The current rating of a microwave oven's capacitor can vary depending on the specific model and its design. However, capacitors used in microwave ovens typically have current ratings ranging from several amps to tens of amps.
It's important to note that working with high voltage and high current components, such as those found in microwave ovens, can be extremely dangerous. Only trained professionals with proper knowledge and expertise should handle or modify microwave oven components. If you have any concerns or issues with your microwave oven, it is recommended to consult a qualified technician or contact the manufacturer for assistance.
