A watt is a unit of electrical power and is equal to one joule per second (1 watt = 1 J s-1). How many hours can a calculator drawing 2.0 × 10-3 watt can be operated by a mercury battery having a cell potential equal to 1.34 V with a mass of 0.22 g of HgO available at the cathode? The cell reaction is HgO(s) + Zn(s) → ZnO(s) + Hg(l)

A business wants to reduce its energy use. One option is to replace ten existing 50 watt fluorescent lights with ten new, 8 watt LED lights that provide the same amount and quality of lighting. The lights are used 12 hours per day, 250 days per year. The cost of electricity is $0.2/kWh. Each LED light costs $1 Assume the new lights last 10 years and that the time frame of the analysis is 10 years. Assume that the electricity...

To illustrate power flow calculations, an extremely simple power system consisting of three buses is shown in Figure 5.1. These three buses are connected through three 345-kV transmission lines 200 km, 150 km, and 150 km long, as shown in Figure 5.1. Similar to the values listed in Table 4-1 of Chapter 4, assume that these transmission...
