If you were to plug a 1200-W heater and a 600-W toaster into a 110-V electrical outlet,what total rms current would these two appliances draw if the wiring is parallel?
A)5.45 A
B)10.9 A
C)11.6 A
D)16.4 A
E)23.1 A

In a parallel circuit, the total current is the sum of the currents through each appliance. The current through each appliance can be found using the formula $I = \frac{P}{V}$, where $I$ is the current, $P$ is the power, and $V$ is the voltage. For the 1200-W heater, $I_{heater} = \frac{1200}{110} = 10.91 \, A$. For the 600-W toaster, $I_{toaster} = \frac{600}{110} = 5.45 \, A$. The total current is $10.91 \, A + 5.45 \, A = 16.36 \, A$, which rounds to $16.4 \, A$.
