I am trying to measure the power consumption of a low power embedded system. As the embedded system consumes current in random pulses from the battery pack, I am using an oscilloscope to analyze the ...
I would like to measure the power consumed by a mains device. I have heard that it's not as trivial as simply measuring the average current, as the device may be resistive, capacitive or inductive, ...
I understand that this is arguably a peripheral electronics problem, but it seemed to fit here better than in physics. I've been doing some power electronics design work with large IGBTs mounted on ...
I was wondering if someone knew how to measure power/current and then interface it to a micro controller to store the data onto some external memory. I basically want to measure the power a device ...
I have a signal which I want to calculate its effective value. The signal is a voltage value read on a 33.3m\$ \Omega \$ resistor connected series to a 220V AC power line. My aim is to calculate the ...
I hope my question is in accordance with the rules of the site. I'm doing a power meter using a voltage transformer, a current transformer and an arduino, besides the components to create the ...
So I'm trying to measure the power consumption of my home PC. I used to have a kill-a-watt meter which I can't find, so I wired up my multimeter to measure the current. Now I'm not sure what to do ...
is it possible to install some device which will measure in real time the torque my diesel engine is providing at the moment?
It is easy to make a meter which will show the engine RPM, many cars have one installed. But to know the power in kW that the engine is providing right now, I also need to know the torque, because: ...
