## Answer to relevant Questions

(a) What is the resistance of an immersion-type heating coil if it is to generate 15 kJ of heat per minute when it is connected to a 120-V source? (b) What would the coil’s resistance have to be if instead 10 kJ of heat ...You are given four A batteries that are rated at 1.5 V each. The batteries are grouped in pairs. In arrangement A, the two batteries in each pair are in series, and then the pairs are connected in parallel. In arrangement B, ...To empty a flooded basement, a water pump must do work (lift the water) at a rate of 2.00 kW. If the pump is wired to a 240-V source and is 84% efficient, (a) How much current does it draw and (b) What is its resistance? Most modern TVs have an “instant warm-up” feature. Even though the set appears to be off, it is “off” only in that there is no picture and audio. To provide a “quick on” feature, the TV’s electronics are kept ...Use Kirchhoff’s loop theorem to explain why a 60-W lightbulb produces more light than one rated at 100 W when they are connected in series to a 120-V source.Post your question
