Cell Circuit Diagram Symbol. Electric circuits can be described in a variety of ways. The connecting lines are used to connect the symbols.
Photoresistor the symbol for a photoresistor or light dependent resistor ldr looks like a resistor in a circle with arrows pointing inwards. An electric circuit is commonly described with mere words like a light bulb is connected to a d cell. Some most commonly used basic electrical symbols in schematic diagrams are shown below.
The idea of a circuit diagram.
Another means of describing a circuit is to simply draw it. In circuits where you have a dual supply that is positive neutral and negative you usually have a third power symbol that looks like the vdd symbol just upside down. The idea of a circuit diagram. A final means of describing an electric circuit is by use of conventional circuit symbols to provide a schematic diagram of the circuit and its components.
