An investigator is using a resistor (a length of nichrome wire in an insulating sheath) connected to a battery to warm a solution in the laboratory. It's a simple circuit: A. What power does the resistor provide to warm the solution? GV V² R P= IV=1²R=- She then decides that this warming is happening too slowly. She has another resistor, but doesn't have another battery. She needs to connect both resistors and the battery into a single circuit. B. Which of the following circuits will provide more power?
