A student connected different numbers of identical 6.0 Ω resistors in series with a 12 V battery. Table shows the student's results.
Table: The total resistance of the circuit and the current in the circuit for different numbers of identical 6.0 Ω resistors connected in series with a 12 V battery
| Number of resistors | Total resistance in Ω\OmegaΩ | Current in A |
|---|---|---|
| 1 | 6.0 | 2.00 |
| 2 | 12.0 | 1.00 |
| 3 | 18.0 | 0.67 |
| 4 |
Complete Table for four resistors connected in series.
Describe the pattern shown by the results in Table 1.
The student now connects two of the 6.0 Ω resistors in parallel with each other, instead of in series. Explain why the current in the battery is now larger than 2.00 A.
