A typical electric water heater has a heating element rated at 4500 Watts and is connected across a 240 Volt power source. When operated normally, find the resistance of the heating element, the current drawn by the heating element, and the cost of heating water for 45.0 minutes. Assume electricity costs $.10/kw * hr
9. + -/8 points SerCP11 17.6.P.041. My Notes + Ask Your Teacher Lightbulb A is marked "40.0 W 120 V," and lightbulb B is marked "75.0 W 120 V." These labels mean that each lightbulb has its respective power delivered to it when it is connected to a constant 120-V source. (a) Find the resistance of each lightbulb. RA= Rg= (b) During what time interval does 2.00 C pass into lightbulb A? (c) Is this charge different upon its exit...
Part A : The resistance of an electric heater is 90 Ω when connected to 120 V. How much energy does it use during 15 min of operation? (answer in J) Part B : The lightbulb used in a computer projector has a resistance of 71 Ω. What is the current through the bulb when it is operating on 120 V? ( answer in A )
