Standard Volt and Ampere

A recent question on here asking about how to calculate the accuracy of a circuit got me thinking about calibration in general. In particular, as EEs we routinely use volts and amperes as a unit and yet these are both rather vague and hard things to…

Why are high power LEDs categorized by wattage, not voltage & amperage?

In searching for the correct replacement LED for a project, I've noticed that, more often than not, high power LEDs seem to be primarily categorized by their wattage. Why is this the standard? It would seem that voltage and amperage would be more…

240 volts circuit amp

Basic question, but I have a doubt! I have a pool heater that works from 240 volts. In order to calculate the annual operating cost, I installed a device that measures amperage and adds up the total consumption. The device measures by induction…

Is there an electronic version of this mechanical system?

I'm asking this question in this way because I don't know any other way to explain what I'm trying to do. Imagine you have 2 gears, gear A and gear B, gear B is 3 times larger then gear A. So, if gear A rotates one full turn, gear B rotates 1/3 of a…

Powering a 1 watt LED using a 3 V coin cell

I was hoping to power a 1 watt LED (would be great if this is capable of powering 2 or 3 watt LEDs) with a 3 volt coin cell. Will the coin cell be able to output voltages and amperages that are within acceptable levels for the LED's operation?…

Is it wattage that kills you and not specifically amps

First of all the actual amounts needed to kill and the body resistance is not important for this scenario. Let's say we are working with dc. Let's say that 100ma is enough to kill across the chest give or take. Let's say we have a generator with a…
