Ground: answer key, US style, sheet 2 of 2

  1. Fig. 1

    1

    Name Earth ground

    In the convention used here, three horizontal lines of decreasing length identify a connection to earth. Check a drawing's legend: the same shape is sometimes used more generally for circuit ground.

  2. Fig. 2

    1

    Name Chassis ground

    The chassis symbol (hatched) marks a connection to the equipment's metal frame or enclosure.

  3. Fig. 3

    1

    Name Signal reference (common)

    The signal-reference symbol marks the chosen zero-volt reference for circuit voltages. It need not be connected to earth or chassis.

  4. Fig. 4

    1

    Name Earth ground

    In the convention used here, three horizontal lines of decreasing length identify a connection to earth. Check a drawing's legend: the same shape is sometimes used more generally for circuit ground.

  5. Fig. 5

    1

    Name Chassis ground

    The chassis symbol (hatched) marks a connection to the equipment's metal frame or enclosure.

  6. Fig. 6

    1

    Name Signal reference (common)

    The signal-reference symbol marks the chosen zero-volt reference for circuit voltages. It need not be connected to earth or chassis.

Notes

  1. Answer key for sheet 1. The Fig. numbers match the exercise.
  2. Rotating or mirroring a whole symbol, with its terminal identities and connections preserved, does not change the component. The terminal labels move with the drawing.
