Question

drag the tiles to the correct boxes to complete the pairs. match the symbols used in electric circuit diagrams to their functions. a device that starts or stops the flow of current a device that provides energy to a circuit a device that glows when it receives current a device that converts electric energy into sound energy

Explanation:

The first symbol (two parallel - lines with a break in the middle) is a cell which provides energy to a circuit. The second symbol (a line with a break and two circles) is a switch that starts or stops the flow of current. The third symbol (a semi - circular shape) is a buzzer which converts electric energy into sound energy. The fourth symbol (a circle with an 'X' inside) is a bulb that glows when it receives current.

Answer:

• a device that starts or stops the flow of current: the second symbol (switch)
• a device that provides energy to a circuit: the first symbol (cell)
• a device that glows when it receives current: the fourth symbol (bulb)
• a device that converts electric energy into sound energy: the third symbol (buzzer)
