Wires, junctions and meters: answer key, US style, sheet 2 of 2

  1. Fig. 1

    Name Wire junction

    In the drawing convention used here, a dot marks a wire connection and a plain four-way crossing without a dot is not connected. Older drawings may use another convention, so check their legend.

  2. Fig. 2

    Name Wires crossing, not connected

    In the newer convention used here, wires that cross with no dot are not connected. Older schematics drew connected wires as a plain crossing and made unconnected wires hop over each other with a small half-circle, so check a drawing's legend.

  3. Fig. 3

    +−

    Name Voltmeter

    A voltmeter is drawn as a circle with a V and is connected across (in parallel with) the part it measures.

  4. Fig. 4

    +−

    Name Ammeter

    An ammeter is drawn as a circle with an A and is connected in line with (in series with) the current it measures.

  5. Fig. 5

    12

    Name Lamp

    The incandescent-lamp convention used on this sheet is a circle with a cross inside.

  6. Fig. 6

    12

    Name Motor

    One common motor convention is a circle containing M; this sheet uses that form.
