Circuits and magnetism refresher — Homework
Use V = I x R for circuit problems, and the like-repel/opposite-attract rule for magnets.
- 1.A circuit has a 6 V battery and a 2 ohm resistor. Find the current.
- 2.A circuit has a current of 4 A through a 3 ohm resistor. Find the voltage.
- 3.In a parallel circuit with two branches, is the voltage the same across both, or does it divide?
- 4.Why do two bar magnets snap together strongly when a north pole faces a south pole?
- 5.Describe what you think would happen to a compass needle brought close to a strong bar magnet, and why.
