You want to plug in a light bulb (p=100W), an electric heater (1500 W), your laptop (65W) and a hair dryer (1200 W) into the same power strip. Assuming the voltage supplied to the outlet is 120V from the power company, can you plug in thee of these into the power strip if it has a fuse rated at 12A. If so, what devices can you plug in? please show work. (hint: these devices will be connected in parallel with respect to each other)
