Standard USB phone charges are 5 V. There are two common types of charger, 1 A and 2.1 A. A 1 A charger is capabable of delivering up to 1 A of current. A 2.1 A charged can deliver more. 1. What is the maximum power each charger can output? 2. If a phone is connected to a standard USB charger and draws 2.1 A of current, what is the phone’s resistance? 3. Some phone manufacturers make USB chargers that...
Supply & Demand, Equilibrium, and Surplus 1. Consider a specific market for smart phone plans (not the phones) in a small town. Here are the conditions: Q = 50 – 0.5 * P Q = –25 + P a. Is the first one the supply or demand curve? How can you tell? (hint: solve for P first) b. At what price will the market be in equilibrium? How many transactions (quantity) will take place? c. If the current price is...
Using Smart Phones in public spaces Smart Phones are simply small computers that can initiate phone calls as well as connect to the internet. Users can use them to pay bills electronically after passing account names and passwords to a financial site/service. However, when used in public spaces, restaurants, or hot spots, hackers can monitor ALL information “in the clear” and therefore capture your logon account and password. What recommendations do you have regarding if/when/how to pay bills electronically?
