What does a curved line symbol mean?
A tilde is a character on a keyboard that looks like a wavy line (~). When you put a tilde before a number, for example, you’re saying that the number is approximate. If you wanted to say that your club had about $1,500 in the bank, you could use a tilde to write that the club had ~$1,500.
What does squiggly line mean in electrical?
Capacitors (parallel lines) store energy in your system, while resistors (zigzag lines) reduce current flow. All electrical engineering students should become familiar with these three shapes, as they are universally used in circuit diagrams.
What does V mean electrical?
The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.

What are the symbols of an electrical switch?
a b RVSS 2 = DOUBLE POLE SWITCH 3 = THREE-WAY SWITCH 4 = FOUR-WAY SWITCH K = KEY OPERATED SWITCH F = SWITCH AND FUSESTAT HOLDER P = SWITCH AND PILOT LIGHT T = THERMOSTAT D = DIMMER SWITCH L = LOW VOLTAGE LIGHT SWITCH M = MANUAL MOTOR STARTER SINGLE POLE SWITCH b = DEVICE SWITCHED DESIGNATION = CIRCUIT DESIGNATION
When do you use a one line diagram?
One-line diagram – a diagram that uses single lines and graphic symbols to indicate the path and components of an electrical circuit. One-line diagrams are used when information about a circuit is required but detail of the actual wire connections and operation of the circuit are not. 2 Line Diagrams
