1. The problem statement, all variables and given/known data 1. Suppose you left a 100 watt light bulb on for one month. If the electricity generation and transmission is 30% effective how much chemical energy in joules was wasted at the power plant for this oversight ? 2. If electricty is generated at 10,000 volts and is to be transmitted at 130,000 volts what should be the turns ratio of the transformer? 2. Relevant equations 3. The attempt at a solution 1. attempt failed.
