Capacitor: answer key, IEC style, sheet 2 of 2

  1. Fig. 1

    12

    Name Capacitor

    A capacitor symbol stands for two conductors separated by an insulator; the two parallel plates are a picture of that.

  2. Fig. 2

    +−

    Name Polarised capacitor

    In the polarised capacitor drawings here, + marks the positive terminal. The US form has a curved negative plate; the IEC form has a hollow positive plate. The marked polarity must be respected.

  3. Fig. 3

    12

    Name Variable capacitor

    In the variable-capacitor convention used here, a diagonal arrow through the plates indicates adjustable capacitance.

  4. Fig. 4

    12

    Name Capacitor

    A capacitor symbol stands for two conductors separated by an insulator; the two parallel plates are a picture of that.

  5. Fig. 5

    +−

    Name Polarised capacitor

    In the polarised capacitor drawings here, + marks the positive terminal. The US form has a curved negative plate; the IEC form has a hollow positive plate. The marked polarity must be respected.

  6. Fig. 6

    12

    Name Variable capacitor

    In the variable-capacitor convention used here, a diagonal arrow through the plates indicates adjustable capacitance.

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.
