Suppose your waffle iron is rated at 1.20 kW when connected to a 3.60 ✕ 102 V source. (a) What current does the waffle iron carry? A (b) What is its resistance? Ω
battery that can deliver a cu (a) What is the total energy, in kilowatt-hours, stored in a 9-V battery rated at 47 A h? Batteries are rated in terms of ampere-hours (A h). For example, a rrent of 3.0 A for 5.0 h is rated at 15 A·h. kWh (b) At $0.19 per kilowatt-hour, what is the value of the electricity that can be produced by this battery?
Batteries are rated in terms of ampere-hours (A·h). For example, a battery that can produce a current of 2.00 A for 3.00 h is rated at 6.00 A·h. (a) What is the total energy stored in a 9.0 V battery rated at 51.0 A·h? kWh (b) At $0.0630 per kilowatt-hour, what is the value of the electricity produced by this battery? NOTE: Enter your response with hundredths precision. cents.gif
