Plan and conduct controlled scientific investigations to determine the relationship between the current and potential drop (voltage) across an Ohmic resistor. Analyze and interpret data to verify Ohm’s law, including constructing an appropriate graph in order to draw a line-of-best-fit whose calculated slope will yield R, the resistance of the resistor.
- Interactions and Energy
The student will demonstrate an understanding of how the interactions among objects can be explained and predicted using the concept of the conservation of energy.
During electric circuit interactions, electrical energy (energy stored in a battery or energy transmitted by a current) is transformed into other forms of energy and transferred to circuit devices and the surroundings. Charged particles and magnets create fields that store energy. Magnetic fields exert forces on moving charged particles. Changing magnetic fields cause electrons in wires to move, creating current.
