Question

Which of the following symbols is used for capacitance in circuits?
A)
 
B)
  

C)


D)

Answer 1

Hint: The symbol itself shows the meaning of what they are. When analysing the components deeply, the working principle and arrangements have similarities with the symbols which denote the component. Capacitors have two parallel plates arranged within it.

Complete step by step solution:
Let's discuss some components and how to denote all those in an electrical circuit with the help of a diagram:

Capacitor: We all know about electric current, conductance, and resistance. But, the capacitance is another important part of understanding the concept of electricity. Capacitors are capable of storing electric charge. A capacitor is a passive electronic component that stores energy in the form of an electrostatic field.
In its simplest form, a capacitor consists of two conducting plates separated by an insulating material called the dielectric. The capacitance is directly proportional to the surface areas of the plates, and is inversely proportional to the separation between the plates.

Now we know that the capacitor is an arrangement of two parallel plates. And from that information we can understand how a capacitor is denoted or what the symbol of a capacitor is in an electric circuit.
We can see the capacitor denoted as two parallel line in the circuit
That is,

So, the final Answer is Option (B).

Note: The other three symbols are:
Resistor: We know, a resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. Ohm’s law states that current flowing through a material is directly proportional to voltage applied across that material and the proportionality constant is the resistance of the material at a constant temperature.
Resistor is denoted by the symbol:
 
Electric Switch is denoted by the symbol:

DC supply is denoted by the symbol:
