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 can decrease resistance by making the wire thicker or shorter, not smaller.)
10. The current running through a circuit is 10 amps from a 5 V battery. Calculate the resistance.
- b. 0.5 Ohms (Using Ohm's Law: Resistance (R) = Voltage (V) / Current (I) = 5V / 10A = 0.5 Ohms.)
