Amperage, Wattage, and Voltage Amperage is a measure of the amount of electricity that is moving through a circuit, whereas voltage is a measure of the force pushing the electricity. The wattage W consumed by an electrical device can be determined by calculating the product of the amperage I and voltage V. (Source: Wilcox, G. and C. Hesselberth, Electricity for Engineering Technology, Allyn & Bacon) (a) A household circuit has voltage V = 163 sin(120st) when an incandescent light bulb is turned on with amperage I = 1.23 sin(120st). Graph the wattage W = V. I consumed by the light bulb in the window (0, 0.054] by (0, 300). Use DESMOS to graph W. (Take a screenshot of your graph or save a picture.) (b) Determine the maximum and minimum wattages used by the light bulb. (On your picture, label the maximum and minimum wattages; it is okay to print or use a stylist) (c) Use identities to determine values for a, c. and v so that W- acos/wt) + c(Use Product-to-Sum Identities to find values for a, b, and c. Take a picture of your work or type your solution in the thread by using Rich Content editor) (d) Check by graphing both expressions for W on the same coordinate axes. (Use Demos again and plot graphs together) (e) Use the graph to estimate the average wattage used by the light. For how many watts (to the nearest integer) would this incandescent light bulb be rated? (Write your estimation in the thread and how you determined them.)
