| - | * The circuit is in a steady state - which means the current should be the same in all three sections. | + | * The circuit is in a steady state: This allows |
| - | * Approximating the battery as a mechanical battery. | + | * Approximating the battery as a mechanical battery: Batteries normally dont keep their energy forever and slowly die over time. Using a mechanical battery means our battery produces a steady source of energy in this problem. |
| - | * The wire has a circular cross-section. | + | * No outside influence on the circuit: This simplifies the model and isolates our circuit from any outside sources |
| - | * No outside influence on the circuit. | + | |
| - | * The wire is made of the same material throughout. | + | |
