A number of typical wall outlets in a room are all on the same
circuit breaker. In one outlet
you plug in a string of 30 lightbulbs, connected in series. Each
lightbulb has a 2-ohm resistance.
In the other outlet you plug in a neon sign that uses a 1:10
step-up transformer. The neon sign
consumes 600 W.
A) If your electricity costs $0.15 per kW hr, how much per day will
it cost you to keep both of
these always turned on? (both the string and the sign, day and
night both)
B) You are worried that the circuit breaker for the room might
trip. Show a calculation of the
rms current that passes through the room's circuit breaker.
(Reminder: there is a transformer
on the Neon sign.)
