A device that runs on AC current it's voltage inside is measured by always turning the multimeter's knob to AC voltage:same for DC right?
I've bought a cheap multimeter and it's not automatic. I've to manually rotate the knob. I live in North America. AC current is used in my home. Does this mean I can always measure voltage by turning ...
I want to sense the On/Off state of an electrical appliance (e.g. light bulb 100W) using a microcontroller ATmega16L. How do i go about doing this? My mains supply specs are 230V, 50Hz
I need to measure the peak to peak voltage and DC offset of a 1Hz to 1MHz sine/triangle wave. The signals amplitude varies between 0 and 2Vpp and the offset can vary between -2v and +5v. I will be ...
