Science Investigation (Physics) -- Heating Effect of a Electrical Current Planning: I will investigate the relationship between the current pass through water and rise the temperature of the water. I will control variables including: the mass of water in the beaker, the voltage, whether the beaker is insulated or not, the time duration used to obtain the results. I will change the values of the resistor. The initial value of the resistor is 3 ?, I will start off from 3 ? and the final value I will take is 10 ?. I will do increments of 1 ?, therefore I will be able to obtain 7 results and it will be sufficient for me to prove my prediction. Instead of using practical apparatus, I used a computer simulation to investigate the relationship between electrical current and the raise in temperature. The only tool we need for this experiment is that computer...
