Answer
* **Question 1:** When you connect three 12V batteries in series, the total voltage is the sum of the individual voltages. Therefore, 12V + 12V + 12V = 36V. The correct answer is (d).<br /><br />* **Question 8:** Ohm's Law states V = IR, where V is voltage, I is current, and R is resistance. We need to find I, so we rearrange the formula to I = V/R. Plugging in the values, I = 120V / 2Ω = 60A. The correct answer is (a).<br /><br />* **Question 19:** Again, using Ohm's Law (V = IR), we want to find R. Rearranging the formula gives us R = V/I. Plugging in the values, R = 12V / 12A = 1Ω. The correct answer is (a).<br /><br />* **Question 10:** The symbol "ol" (which I assume is meant to represent a simple line) represents a connecting (conductive) wire. The correct answer is (d).<br /><br />* **Final Question:** The component used to control current flow in an electrical circuit is a **switch**.<br />
