  • 1

    This opposition to current flow is known as resistance (R), and the unit of measure is the

    ohm

  • 2

    Good conductors will have

    a low resistance

  • 3

    Resistance of the conductor is directly proportional

    to its length

  • 4

    If a resistor cross sectional area is doubled and the length is halved the resistance will be

    quadruple

  • 5

    Electrical Resistivity: it depends only on the material, and is a property of the material and is

    independent of the dimensions of the conductor

  • 6

    If for an increase in temperature the resistance of a material increases, it is said to have

    a positive temperature coefficient

  • 7

    A material whose resistance decreases with an increase in temperature has

    a negative temperature coefficient

  • 8

    Temperature increase most conductors electrical resistance will

    increase

  • 9

    In Color code Resistor the fourth band, which

    is the tolerance

  • 10

    the total circuit resistance (RT) is equal to

    the sum of the individual resistances

  • 11

    This ability of resistance dissipate heat caused by the resistance is

    wattage rating

  • 12

    The heat dissipating capability of a resistor is measured in

    Watts

  • 13

    Conductance is

    directly proportional to area, and inversely proportional to the length of the material

  • 14

    The unit of conductance is the mho (G)

    which is ohm spelled backwards.

  • 15

    When voltage exists but current does not flow because the circuit is open

    no work is done

  • 16

    the basic power formula is

    P = V x I,

  • 17

    If the voltage is increased the power will

    increase

  • 18

    The basic unit of power is the

    watt

  • 19

    Power was expressed by

    alternate pairs three basic quantities V, I, and R.

  • 20

    Maximum power is transfer theorem states; Maximum power is transferred to the load when the internal resistance of the supply

    equal to the resistance of the load

  • 21

    2 thermo elements connected in parallel voltage 28v and current 10amp the power

    560w

  • 22

    The larger the physical size of a carbon resistor

    the higher the wattage rating

  • 23

    One horsepower is equal to

    746 watts

  • 24

    In a series circuit, the total power is equal to

    the SUM of the power dissipated

  • 25

    A circuit has a voltage source that delivers 6 volts and the circuit uses 3 watts of power. What is the resistance of the load? R=v²/p

    12 ohms 3

  • 26

    Capacitance is measured in units called

    farads

  • 27

    Factors Affecting the Value of Capacitance The value of capacitance of a capacitor depends on three factors

    The area (A) of the plates. 2. The distance (d) between the plates. 3. The dielectric constant (permittivity) of the material between the plates.

  • 28

    The specific measure of a material acceptance of magnetic flux is known as

    Permeability

  • 29

    The force between opposite electrical charges

    attraction

  • 30

    The lines of force are polarized

    from positive to negative

  • 31

    Capacitors in Parallel

    CT = C1 + C2 + C3 +…….Cn

  • 32

    Dielectric breakdown force is measured in

    coulomb per square meter

  • 33

    The type of the capacitor used where large amount of capacitance required is called

    electrolytic

  • 34

    A capacitor is a device that stores electrical energy in

    an electrostatic field

  • 35

    The relation between the distance between the plates and the charge is

    inversely proportional

  • 36

    In A variable capacitor (when the plates are over- lapped the capacitance will be

    maximum and the working voltage is decreases

  • 37

    When a capacitor is fully charged and the source voltage is equaled by the counter electromotive force (back-EMF) across the capacitor, the electrostatic field between the plates of the capacitor is

    maximum

  • 38

    Since the electrostatic field is maximum the energy stored in the dielectric

    is also max
