An electric heater draws an average power of 1100 watts when plugged into a 110 V rms outlet. Calculate the resistance of the heater and the rms current.
A)11 Ω, 10 A (rms)
B)110 Ω, 10 A (rms)
C)10 Ω, 11 A (rms)
D)10 Ω, 110 A (rms)
E)0.09 Ω, 11 A (rms)

The resistance of the heater can be calculated using Ohm's law: R = V/I, where V is the voltage and I is the current. The rms current can be calculated using the formula: Irms = P/V, where P is the power. Substituting the given values, we get: R = 110 V / 10 A = 11 Ω and Irms = 1100 W / 110 V = 10 A.
