Question

Which of the following is the symbol of tapping the key?
A.

B.

C.

D. All

Answer 1

Hint: We know that there are various symbols that we use to denote various electrical components in a circuit diagram because we cannot give names of each electric component. In the same way, there are symbols for various types of keys used in an electrical circuit. In the options, we have given symbols for various types of keys. Choose the symbol for the tapping key from them.

Complete answer:
In the given question, we have given different symbols and we have asked to identify the symbol of the tapping key from the given options.In the given options, there are symbols of various types of keys.The symbol shown in the option A is the symbol of a closed plug key in which the plug is inserted or removed to allow or block the electric current in the circuit.Hence, the option A is incorrect.

The symbol shown in option B is the symbol of a switch key in which the inclined line shows the open circuit.Hence, option B is incorrect.The symbol shown in the option C is the symbol of a tapping key as the arrow is used in the symbol for the tapping key. The tapping of this key allows or blocks the electric current in the circuit which is done manually.

Hence, the correct option is C.

Note: The students should perfectly keep in mind the symbols of various electrical components used in the circuit diagram because these symbols are very important to identify the electrical components used in the actual circuit of the circuit diagram shown. If one gets confused between these symbols then he/she will not be able to read the circuit diagram correctly.
