An electric heater designed for export to the US market draws an average power of 1100 Watts when plugged into a typical US 110 V-rms outlet.Calculate the resistance of the heater and the rms current.
A)11 $\Omega$ , 10 A (rms)
B)110 $\Omega$ , 10 A (rms)
C)10 $\Omega$ , 11 A (rms)
D)10 $\Omega$ , 110 A (rms)
E)0.09 $\Omega$ , 11 A (rms)

The resistance of the heater can be calculated using Ohm's law: R = V/I. The rms current can be calculated using the formula: I = P/V. Substituting the given values, we get: R = 110 V / 10 A = 11 ohms. I = 1100 W / 110 V = 10 A (rms).
