4. Google it and use your own words
5. Magnetic field
6. Resistance, conductivity
7. Less than, greater than
8. the resistor decreases the current by transforming electrical energy into different types of energy.
9. Heat energy
10. Not sure still trying to find the answer
11. No
12 13 and 14 still working on it let me know if you find the answer

Hope this helps

Answer 2

13. Electromagnet P

Answer 3

12. The battery is the power source, the on off is the switch, the light bulb is the load, the wire is the conductor.
