Two identical rods transfer a certain amount of heat in 20 s when they are joined end to end (in series). Find the time in seconds taken to transfer the same heat when the same two rods are joined side by side (in parallel) between the same ends.
Answer:
5
Solution:
Series resistance is and parallel resistance is . The rate is 4 times larger, so the time is s.
