I’m in high school and we are going to do this laboratory in which we will have to make two solutions at different concentrations and determine which has the greatest electrical resistance in a circuit (we will connect it with wires to a 9V battery, calculate its amperage and voltage to determine the resistance of each) However, we must also mention the electric energy, the electric power and the energy efficiency in our analysis (lab report). We have to explain why energy can be released as heat in a circuit using the output/input energy formula. We also have to explain why a more concentrated solution has less resistance (using the notion of ions) while stating why energy can be lost through the circuit (using P=UI and E=PdeltaT).
所以我的问题是:
- 在这种类型的电路中(没有电阻器但有解决方案)如何释放热量?
- 如果我们不考虑到热量,这可以如何影响我们的结果或能量。
- 最后,你能解释一下什么使解决方案更有效吗?
