SKETCHING USING SYMBOLS

In a circuit diagram, electrical symbols are used
to represent the components in an electric circuit.

Let’s look at the symbols for the ZAKI
components in an electric circuit.

Sketching using the electrical symbols is easier to understand as compared
to using the pictures of actual components. It shows the connections of the
electrical components more clearly.
