4. A fully-charged power bank with a full capacity of 100,000 mAH is used to supply a DC lamp of 12 ohms at a constant voltage of 24 volts for 35 hours. The said power bank is then used to power up a DC load requiring 3 A for 8 hours. What percentage of the full charge capacity of the power bank remains? If it is now used to charge a cellular phone and was drained in 12 hours, what is the average current requirement of the phone?

WARM WHITE 2700K A-LAMP/E 26 You have a Switch LED Lightbulb with the following information: • It is equivalent to a 75 Watt incandescent lightbulb. • It uses 20 Watts of electricity. • It is estimated to last 25,000 hours. The purchase price of the lightbulb is $51.99. • The package claims an estimated energy cost of $2.41 per year, but this estimate is not based on local electricity costs. Assume that local electricity costs $0.086 per kW-hr. Based on this information, we can now calculate the cost of ownership for this bulb. The cost of ownership is defined as the purchase price of the lightbulb plus the cost of the electricity required to run the lightbulb until failure. Note the equation below: Purchase price + Total electricity cost = Cost of ownership Calculate the cost of ownership for this lightbulb.
