Heating 100ml water with a 2W resistor based element, how close can I get with the well known heat transfer formula?

As it turns out, quite close, I calculated 1.71W which is 16% off 👌🏻🙂

I’m using my #keithly #sourcemeter as a calibrated supply, so the two #eevblog multimeters, measuring heating element voltage and current, aren’t really needed. They’re mostly there for display and bling, however doing this experiment with a regular bench supply, you would need them 🙂
Multiplying the two measured values gives a quite satisfying result though, you should try it 😃

I’m done with #calorimeter experiments for now, other exiting things are queued up in my little lab 🙂

I ended up ordering a more suitable #calorimeter, I want to repeat my previous test with better accuracy.

My #keithly #sourcemeter really is a nice companion when doing things like this, I designed a new resistor heating element meant to run at a higher voltage and I get a precise reading of the power dissipated 👍🏼 Many bench supplies will do this too, but not at the same accuracy.
And accuracy is what I’m looking for in this setup.

The calorimeter was reasonably cheap at Amazon and shipment took 5days including the weekend.

Stay tuned 👌🏻🙂
