AboutDave Nyce Expertise I have been an electronics engineer for 25 years. I can answer questions on analog and digital circuits and my specialty is sensors.
Experience I am the inventor on 23 US patents, and also some foreign ones. Developed sensors for over 25 years. Licensed private pilot (airplane and rotorcraft), have HAM radio license. I'm not an expert in computer networking.
Question I have a sewing machine that was made in England. It is: 230-250 volts and 0-25 amps. I have found a web site where I can buy a converter. However, I do not know the watts of my machine. When I apply OHMS law, the figure is so high, I cannot believe it. Can you help? Thanks, Janet
Answer There is a surge current when starting this type of motor, so the maximum surge current is shown. The current when running is lower. The running power should be about 100 watts. Try to get a converter that says it is ok for running a motor. (This type of motor is called a "universal wound" motor or AC/DC motor.
