    Study Notes

    Reflection on Career and Purpose

    • The author reflects on their career aspirations and how it relates to their life's purpose
    • The idea of having a specific career provides a sense of direction and meaning for their future

    Interest in Electrical Engineering

    • The author is interested in pursuing a career in Electrical Engineering
    • Despite finding the studies challenging, they are committed to pursuing this career

    Career Goals and Expectations

    • The author envisions a life of learning and growth through the journey of pursuing engineering
    • They expect to face ups and downs, which will provide lessons to learn from mistakes
    • The author hopes to achieve financial stability to support themselves and their family

    Problem-Solving and Resilience

    • The author thinks about how they will handle problems and challenges in their career
    • They strive to develop strategies to solve problems quickly and efficiently when faced with difficulties

    Charging Spheres by Induction

    • Induction occurs when an uncharged sphere is brought near a charged object, causing separation of charge.
    • Electrons are repelled, moving to the opposite side of the sphere, creating an induced charge.

    Units of Charge

    • The coulomb (C) is a unit of charge, with 1 C = 6.25 x 10^18 electrons.
    • The charge on a single electron is -1.6 x 10^-19 C.
    • Metric prefixes are often used with the coulomb: 1 μC = 1 x 10^-6 C, 1 nC = 1 x 10^-9 C, and 1 pC = 1 x 10^-12 C.

    Example 1: Calculating Charge

    • If 16 million electrons are removed from a neutral sphere, the charge on the sphere is q = +2.56 pC.

    Coulomb's Law

    • The force of attraction or repulsion between two point charges is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them.
    • The proportionality constant k depends on the choice of units for charge.

    Calculating Electric Force

    • The formula for electric force is F = k * q * q' / r^2, where k = 9 x 10^9 N·m^2/C^2.
    • The value of k can be approximated as 8.9875517923 x 10^9 N·m^2/C^2.

    Example 2: Calculating Electric Force

    • The force between a -5 μC charge and a +3 μC charge, 2 mm apart, can be calculated using Coulomb's Law.

    The Two Types of Charge

    • There are two types of charge: positive and negative.
    • Opposite charges attract, while like charges repel.

    The First Law of Electrostatics

    • Like charges repel, while unlike charges attract.

    Charging by Contact

    • An uncharged electroscope can be charged by bringing a charged rod into contact with it.
    • Electrons move, causing the leaves of the electroscope to separate and the scope to become charged.
    • The scope can be charged positively by using a positively charged glass rod.
