A lamp operates with a current of 0.625A and a potential difference of 120V. What is the currnt flowing through the microwave?
You have aready stated that the current through the LAMP is 0.625 A. If the microwave is some other part of the circuit, it will have the same current if it is in series wth the lamp. If it is in parallel wth the lamp, you need to tell us more about the circuit, including the resistance of the microwave.
