4. The wires can: **n. change length and direction.**
5. The resistors can: **l. increase the resistance of the circuit.**
6. For the electrons to move: **g. the circuit must be closed and have a battery.**
7. The battery can: **f. have the voltage changed.**
8. When using the voltmeter, when the black probe is on the black side of the battery: **b. the voltage is always zero.**
9. When using the voltmeter, when the red probe is on the black side of the battery: **m. the voltage is a positive value.**
10. The eraser can: **d. do not work in the interactive.**
