- In a certain stereo system, each speaker has a resistance of 5.00 Ω. The system is rated at 55.2 W in each channel. Each speaker circuit includes a fuse rated at a maximum current of 4.50 A. Is this system adequately protected against overload? Yes/No Give the current drawn by each speaker to support your answer.Let's say you have a 30W lightbulb that operates on a 120V alternating current. When the light is on the temperature is 2473 celsius. What would be the resistance at 2066 celsius? Note that the temperature coefficient α=4.5x10^-3/celsius1. You run your 1500 W microwave in your dorm room for 5.0 minutes to heat your TV dinner.
