Electric Circuits Homework: R, P, V, I Solutions
I have the final answer but I am afraid I am not understanding how I got there. You said that Req was equal to 20...but where did that number even come from?- ElegantSir

Electric Circuits Homework: R, P, V, I Solutions
Im not quite following...because if I do that i'd be getting the exact same answer: The amperage in R2 is 0.24, and its resistance is 5. That means that 0.24 * 5 = 1.2 volts. Which would mean that 1,2 volts also goes into R3. In R3 if the voltage is 1.2 and the amperage is 0.06, you would plug...- ElegantSir

But if you don't know what R3 is then how are you supposed to find the equivalent??- ElegantSir

Electric Circuits Homework: R, P, V, I Solutions
I know that the amperage had to be 0.06A because the circuit had a total of 0.3A and resistor 2 had 0.24A going through it, so 0.3 - 0.24 = 0.06A for R3. Also after R1, the remaining voltage was 1.2V which was carried to both R2 and R3. I used 1.2V / 0.06A to get a Ω of 20. Im only assuming...- ElegantSir

Electric Circuits Homework: R, P, V, I Solutions
Ahh okay. So for the last two columns of the chart: Resistor 3: 20Ω, 0.06A, 1.2V Resistor 4: 12Ω, 0.06A, 0.6V And then the power would be Ptotal = Vtotal * I total P = 3V * 0.30A P = 0.90 watts Therefore the power of the circuit would be 0.90 watts. I believe this is correct, yes?- ElegantSir

Calculating Energy from Mass Using E=mc²
Ahh I see where I went wrong. The example questions like to use numbers like 1.9 * 10^-4 rather than use the actual whole number so I got confused. I would need to convert grams to kilograms which would mean the number would now become: 1.8884 * 10^-5 Now I plug it into E = mc^2 and get: E =...- ElegantSir

Calculating Energy from Mass Using E=mc²
Im not quite sure what you mean by all of that. I assume you mean I need to convert grams to a different unit of measurement but I am not sure what. Also what do you mean by "I think you are assuming, based on the wording of the question, that only 1 atom of D and T react?"- ElegantSir
