Please draw diagram, asking about question B
B) After the filaments stabilize their temperature, the resistance of one lamp bulb is 240 ohms,
and the other lamp bulb is 360 ohms. How much current can you draw from the other devices
in your room without tripping the (10A) circuit breaker?
C) You realize that you could save some money by switching to LED bulbs. Suppose you replace
the two bulbs with one 2W LED and one 4W LED, Calculate vour savings each month if the
