1. The problem statement, all variables and given/known data In a household, the wife reads a book that uses a light bulb that has a resistance of 100Ω and is connected to a 100 V line while the husband watches a TV that draws 100 W of power. They do these actives for 200 mins. Power comes from a wind generator that charges batteries. The wind supplies 10 amperes at a voltage of 100 V. How long must the wind blow to recharge the battery. 2. Relevant equations V=IR P= V2/r 3. The attempt at a solution Modeled the circuit to have the light bulb and tv in parrallel. Using the power equation, the tv also has 100Ω of resistance which doesn't make to much sense to me. Power is J/s so we know that 200 min is 12000s which tell us 1.2 MJ is required to charge the battery.
