Problem

An electric kettle is labeled “1500 W, 120 V1500\,\text{W},\ 120\,\text{V}.” To operate it from a 240 V240\,\text{V} outlet without exceeding its rated power, a resistor is placed in series with the kettle. What should the resistance of this additional resistor be? (a) 19.2 Ω19.2\,\Omega (b) 4.8 Ω4.8\,\Omega (c) 9.6 Ω9.6\,\Omega (d) 38.4 Ω38.4\,\Omega
