Overview

How do defibrillators you see on TV actually work? Physics can explain! In this video, Dr. Shini has the task of breaking down electrical potential energy, electric potential, voltage, capacitors, energy storage, and potential energy.

    SC15.PHYS.11

    Develop and use models to illustrate electric and magnetic fields, including how each is created (e.g., charging by either conduction or induction and polarizing; sketching field lines for situations such as point charges, a charged straight wire, or a current carrying wires such as solenoids; calculating the forces due to Coulomb’s laws), and predict the motion of charged particles in each field and the energy required to move a charge between two points in each field.

    Knowledge

    Students know:
    • How to develop and use models.
    • Understanding of static electricity.
    • Phenomena of electric and magnetic fields.
    • How charges interact and how they behave in a field.
    • How fields interact.

    Skills

    Students are able to:
    • Properly use a voltmeter or mulimeter.
    • Develop and use models to make predictions and to illustrate explanations.

    Understanding

    Students understand that:
    • Some forces act over a distance, creating fields.
    • The behavior of objects in a field is predictable and caused by interaction of fields and charged particles.
