The 100-bulb strand of incandescent Christmas lights is rated at 40.8W of power. When stacked, two strands consume twice the power (81.6W =2 x 40.8W) and act as two resistors in parallel to a 120V source. If the 120V source is safe guarded by a 15A circuit breaker, and the 15A circuit breaker will actually "trip" (open up) at 80% its rating (which is often the case in the real world!), how many strands can be run at the same time without tripping the circuit breaker? If you use 100-bulb strands of LED Christmas lights instead, how many strands can you run at the same time? Assume LEDs run at 1/10th the power of incandescent bulbs.

Hi, Here's my question. 26.45: An emf source (e=120 V), a resistor (R=80.0 W), and a capacitor (C=4.00 mF) are connected in series. As the capacitor charges, what is the magnitude of the charge on each plate of the capacitor when the current in the resistor is 0.900 A? Hint: From the information given, first calculate the voltage across the capacitor when the 0.900 A current flows in the circuit. Then use the voltage as a function of the time equation for a charging capacitor in an R-C circuit.
