A circuit symbol drawn as a dome shape with a flat top on a horizontal line.

  • A.bell
  • B.buzzer
  • C.circuit breaker
  • D.panic lamp

Answer: B

The symbol shown, a dome-shaped outline fixed on a line, is the electrical symbol of a buzzer, a device that gives a continuous sound when it is supplied with a voltage. A bell is drawn as a similar dome with a clapper, a circuit breaker is drawn as a switch with a contact, and a panic lamp is drawn as a lamp symbol. The answer is buzzer, option (B), and the item depends on recognising the symbol.
