hard · Enhanced ACT science
A student built a simple circuit with a battery and two resistors, R1 and R2, and measured current through each arrangement:
| Arrangement | R1 (Ω) | R2 (Ω) | Total current (A) |
|---|---|---|---|
| Series | 4 | 8 | 1.0 |
| Parallel | 4 | 8 | 4.5 |
Based on the data, what is the voltage of the battery?
- 6 volts
- 12 volts
- 24 volts
- 36 volts
