    Consist of neutron, protons and electrons

    atoms

  • 6

    Neutron and protons are located the?

    nucleus

  • 7

    An element consist of

    one kind of atoms

  • 8

    Electrons have a

    negative charge

  • 9

    The nucleus of atoms has

    protons and neutrons

  • 10

    A conductor of electricity is a material that

    allows the electrons to move through it

  • 11

    Atoms consist 3 still smaller particules

    electron, protons and neutrons

  • 12

    Of this three particles, the positive side charge is the

    proton

  • 13

    And the negatively charge particle is the

    electron

  • 14

    Particle found on the nucleus of the atom are the and the

    proton and neutron

  • 15

    An atom that has gained a surplus of electrons is said to be

    negative charge

  • 16

    And if the atom has lost a number of electrons, it is called a

    positive charge

  • 17

    The electrons found in the outermost orbit of the atoms are known as

    valence electrons

  • 18

    Most insulation are

    compound of two or more elements

  • 19

    Voltage is

    electrical force

  • 20

    Resistance of a conductor is determined by

    length, cross-sectional area, temperature and type of material

  • 21

    A current is electrical

    flow

  • 22

    Which of the form of voltage source require polarity markings

    direct current

  • 23

    Technician should wear static straps when working on any electronic components to prevent discharge of damaging voltage that are produced by

    friction

  • 24

    The flowing symble is

    rheostat

  • 25

    The following symble is

    motor

  • 26

    A break in the normal path of an electron circuit causes a/an:

    open circuit

  • 27

    Amount of current is determined by

    source voltage and resistance of the circuit

  • 28

    If an open occurs in a circuit, current is

    decrease

  • 29

    As applied voltage increases

    current increases

  • 30

    Voltage is

    potential difference

  • 31

    Resistance is

    determined by circuit construction

  • 32

    Amperage is

    measurement of current

  • 33

    Resistance of a circuit decrease if a/an

    short occurs in a series or parallel circuit

  • 34

    As resistance of a circuit increases

    current increases

  • 35

    If a resistor in a circuit is shorted, an ammeter in the circuit would indicate

    more current flow

  • 36

    In heavy equipments electrical system, a resistor could be

    any of the above

  • 37

    Reduced current flow in a series circuit can be caused by

    corroded
