you have set up a parallel circuit with three leds. you want to determine what the voltage of one of the leds is. what piece of equipment would you need? @aibot
To determine the voltage of one of the LEDs in a parallel circuit, you would need a voltmeter. A voltmeter is a measuring instrument used to measure the voltage or potential difference across a component or set of components in an electrical circuit. By connecting the voltmeter in parallel with the LED whose voltage you want to measure, you can obtain an accurate reading of its voltage.
