Based on just what you have given, let's look at a couple possible scenarios.We know that the total current is 20A and the total resistor is 5 Ohm and the voltage is 100 Volt.
How to calculate resistors and the current on R1 , R2, R3
Thanks
Now you seem to be throwing out additional information that wasn't in the first post? You can't expect much meaningful help if you don't include all the information.resistor (R1) emits an effect twice the size
like the other (R2). The third (R3) emits a power of 1.2 kW.
That's not correct, but I can't tell you where you made your mistake unless you show your work.R3 = 8,3 Ohm
Engineering is not about guessing. By guessing a value and then basic the rest of your work off that, you pretty much guarantee that all of your results will be wrong.No basis on what I gave R1 the value 1 ohm, but only to get close to find the values of the other resistors.
Knowing that R1 and R2 are dissipating 800 watts total, you can calculate the power of each resistor.The total should be 2000 Watt, and since R3 dissipate 1200 watt so R1 and R2 dissipate 800 watt!
The problem is that you don't understand Ohm's Law or the power equation.The calculation is based on Ohm law, but the total resistance is 5 Ohm
