This happened to me when i started using my desktop power supply.
Measure power consumption with multimeter.
A multimeter is an essential tool in any electronics lab.
What i d like to know is if it is possible to do this sort of measurement with a multimeter perhaps just by wiring the multimeter to the head of the power chord then plugging it in and measuring the current of amps.
I had a dc motor that needed 3a current to start after it was running the current use dropped back to under 1a.
Ya the kill a watt meters are not the greatest.
I want to use an inexpensive multimeter to measure the average power consumption in an appliance computer.
In this video you know about calculating ac volts amps and power consumption of your electronics.
You ve learned how to measure voltage current and resistance and how to check continuity.
Your multimeter might not be fast enough to register this and might not notice this if the power supply can handle this.
Available from amazon home depot hardware stores and other retailers for around 20 40 this power meter will let you take an accurate measurement of your pc s power consumption.
If you re looking for a multimeter you may found this post useful best multimeters under 50.
Furthermore measuring anything over 10 amps could blow a fuse or destroy the multimeter as well.
Your multimeter might have completely separate ports for measuring amps while the other port is specifically just for voltage resistance and continuity but most cheaper multimeters will share ports.
In this beginner s guide we ve shown you how to use a multimeter.
The kill a watt meter measures kilowatts and kilowatt hours.
