An anti-condensation panel contains two identical resistor strips. A technician connects the strips to a 12.0 V d.c. supply in two arrangements.
| Arrangement | Number of resistor strips | Supply potential difference in V | Total current from the supply in A |
|---|---|---|---|
| P | 1 | 12.0 | 1.50 |
| Q | 2 | 12.0 | 3.00 |
Calculate the total resistance of each arrangement.
Explain how the resistor strips are connected in arrangement Q.
