You are building an off grid house fitted with solar panels and a battery bank. The house operates at 120V and uses 20kWh of energy per day. The battery needs to be able to store an entire day of electricity. What should be the capacity of the battery in Ah? Assume the battery has a round trip efficiency of 87%. Please show your work!

You are an electrician installing the wiring in a new home. The homeowner desires that a ceiling fan with light kits be installed in five different rooms. Each fan contains a light kit that can accommodate four 60-watt lamps. Each fan motor draws a current of 1.8 amperes when operated on high speed. It is assumed that each fan can operate more than three hours at a time and therefore must be considered a continuous-duty device. The fans are to be connected to a 15-ampere circuit. Because the devices are continuous-duty, the circuit current must be limited to 80% of the continuous connected load. How many fans can be connected to a single 15-ampere circuit? How many circuits will be required to supply power to all five fans?
The values of the circuit elements are given below. What is the average power transferred to resistor R2? R1=250 ohms C=6 micro F L=0.6H R2=2000 ohms
