TERM 2 CYCLE 2.2 - ELECTRICAL CIRCUIT SYMBOLS

Open Ended

Imagine a world without symbols... How would we identify and understand things around us?

Multiple Choice

Why are symbols significant in our daily lives?

• They make communication faster and easier.

• They are only used in mathematics.

• They complicate understanding.

• They are not important in modern society.
