Final answer:
The power and potential difference for a device with a resistance of 11 ohms and a current of 12 amps are 1584 watts and 132 volts, respectively.
Step-by-step explanation:
The power and potential difference for a device with a resistance of 11 ohms and a current of 12 amps can be calculated using Ohm’s law and the power formula. According to Ohm's law, potential difference (V) can be found with the formula V = IR, where I is current and R is resistance. This gives us V = 12 A × 11 Ω = 132 V. Furthermore, the power (P) dissipated by the resistor can be calculated using P = I²R, which leads to P = (12 A)² × 11 Ω = 1584 W.
