A student uses a data logger to measure the total charge that has flowed through a resistor. The current in the resistor is constant.
The Table shows her results.
Table
| Time in s\text{s}s | 0 | 30 | 60 | 90 | 120 |
|---|---|---|---|---|---|
| Total charge in C\text{C}C | 0 | 12 | 24 | 40 | 48 |
Identify the anomalous result in the Table.
Describe the relationship between the total charge and the time.
Use data from the Table in your answer.
Calculate the current in the resistor.
Suggest what the student should do about the anomalous result.
