Answer to relevant QuestionsA battery delivers 2.54 A to a resistor rated at 4.52Ω. When it is connected to a 2.21-Ω resistor, it delivers 4.98 A. Determine the battery’s (a) Internal resistance (assumed constant), (b) Emf, and (c) Terminal ...The tungsten filament of an incandescent lamp has a resistance of 200 Ω at room temperature. (a) What would the resistance be at an operating temperature of 1600oC? (b) Assuming it is plugged into a 120-V outlet, what is ...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. Draw the circuit diagrams indicating the correct placement for the ammeter in the following situations. (Use a circle with an “A” in it to represent the ammeter.) (a) Three resistors are wired in parallel and you want ...What is the equivalent resistance between points A and B in Fig. 18.29?
