### Science

SP5

Obtain, evaluate, and communicate information about electrical and magnetic force interactions.

SP5.d

Plan and carry out an investigation of the relationship between voltage, current, and power for direct current circuits.

SPS10

Obtain, evaluate, and communicate information to explain the properties of and relationships between electricity and magnetism.

SPS10.a

Use mathematical and computational thinking to support a claim regarding relationships among voltage, current, and resistance.

-Explain the movement of electric charges through a conductor.

-Explore how electric potential relates to voltage and the movement of charges through a wire.

-Relate how an electric field is created within a wire to how that drives current flow.

-Understand the relationship between current, voltage, and resistance for a given circuit. Relate this understanding to Ohm’s law.

current (I) - the flow of electric charge per unit time; SI unit is the ampere (A).

current electricity - the flow of electric charge.

electric potential (V) - also known as voltage, the energy capacity of a unit of charge; the SI unit is the volt (V).

resistance (R) - the opposition of a material to the flow of electric current; the SI unit is the ohm (Ω).

static electricity - the accumulation of electric charge on the surface of or within a material.
