Answer: The subordinating conjunction is the word though, which has the meaning of <em>contrast or opposition</em>, the same as <em>but</em>. <em>Though</em> can also be used to <em>link two main clauses</em>, with the meaning of<em> "but" or "yet"</em>: <em>He says he will</em> <em>pay, thought I don't think he will</em>. Words that introduce adverb clauses are called subordinating conjunctions.
By comparing (1) and (2), we see that the current in the parallel configuration is greater than in the series configuration. Therefore, the correct answer is false.
