Question

A microwave oven is connected to 200V supply and it draws 10A

Answer 1

Answer:

Microwave ovens are typically rated in watts; often this is shown on the serial number plate. Or you can look it up on-line based on the model number.

Divide the number of watts by your line voltage (e.g. 110v in the US) to get amps, because P (power) = V (volts) x I (current).

So a 1100 watt oven / 110 volts is 10 amps.
