Here are the answers to your questions:
3. Which of the following materials are good conductors? (Select all that apply)
- **a** copper
- **b** gold
4. Which of the following materials is considered an insulator? (Select all that apply)
- **b** rubber
- **c** wood
5. Which of the following are characteristics of a good conductor? (Select all that apply.)
- **a** Conducts electricity
- **c** Allows electrons to flow easily
6. When salt is dissolved into water, it can become a better conductor of electricity.
- **True**
7. In which kind of material is charge most easily transferred?
- **a** conductors
8. What is the relationship between voltage and current (assuming the resistance stays the same)?
- **c** If the voltage increases, the current increases
9. You can decrease resistance by making the wire in a circuit smaller.
- **False** (You decrease resistance by making the wire longer and thicker, not smaller)
10. The current running through a circuit is 10 amps from a 5 V battery. Calculate the resistance.
Using Ohm’s law (V = IR), we can rearrange to calculate resistance (R = V/I):
- \( R = \frac{5 \text{ V}}{10 \text{ A}} = 0.5 \text{ Ohms} \)
- **A) 0.5 Ohms**
