In the last tutorial, we discussed Ohms law and we saw the relation between Voltage, Resistance and Current.
Joules, an English physicist and brewer (beer and science: the perfect couple 😉 ), found out that something else had a direct relation to current and resistance: heat.
A lot of people don’t start with electronics because they think that it involves a lot of mathematics and they are correct. However, you don´t need a higher degree in maths, you are already halfway if you can find the on-and-off-switch of your pocket calculator.
If you still have doubts then read on and you will see how easy it is.
