This document provides information about electric circuits and electricity. It defines electric current as the flow of electric charges along a path. It notes that Alessandro Volta invented the battery and the unit of electric current is the ampere. There are two main types of electric circuits: series circuits where the components are connected one after another, and parallel circuits where there are two or more pathways and components are connected parallel to each other. The document also includes electric circuit symbols and has students match components to their corresponding symbols.

2. STUDENTS WILL BE ABLE TO
 UNDERSTAND ELECTRIC CIRCUIT
 UNDERSTAND TYPES OF ELECTRIC
CIRCUIT
 UNDERSTAND WHAT IS ELECTRIC
CURRENT

3. Q)WHO INVENTED ELECTRICITY?
Q)WHAT IS THE UNIT OF ELECTRIC
CURRENT?
Q)WHO INVENTED BULB?

4. A1) Italian physicist Alessandro Volta
A2)AMPERE
A3)THOMAS EDISON

5. a form of energy resulting from the existence of
charged particles (such as electrons or protons),
either statically as an accumulation of charge or
dynamically as a current

6. MANY GADGETS,MACHINES AND DEVICES
IN THE MODERN WORLD USE ELECTRICAL
ENERGY TO WORK.
SOME EXAMPLES ARE:
 TELEVISION
 ELECTRIC LAMPS
 ELECTRIC FANS

7. AN ELECTRIC CURRENT IS THE PATH
ALONG WHICH ELECTRIC CHARGES
FLOW.IT CONSISTS OF A SOURCE OF
ELECTRICAL ENERGY SUCH AS AN CELL OR
BATTERY,WHICH DRIVES THE ELECTRIC
CURRENT THROUGH THE
CIRCUIT,CONNECTING WIRES AND
ELECTRICAL COMPONENTS SUCH AS BULBS
AND SWITCHES.

8. THERE ARE TWO TYPES OF CIRCUIT.
 SERIES CIRCUIT :
A SERIES CIRCUIT IS A CIRCUIT WHICH HAS ONLY
ONE PATHWAY AND COMPONENTS ARE
CONNECTED ONE AFTER ANOTHER.
 PARALLEL CIRCUIT :
A PARALLEL CIRCUIT IS A CIRCUIT WHICH HAS 2
OR MORE THAN TWO PATWAYS AND
COMPONENETS ARE CONNECTED PARALLEL TO
EACH OTHER.

9. A PERSON WHO CANNOT MAKE PERFECT
COMPONENTS IN DRAWING SO HE CAN USE
SYMBOLS INSTEAD OF DRAWING A
PARTICULAR COMPONENT.EVERY
COMPONENT HAVE THEIR OWN SYMBOLS.
THE LIST IS SHOWN IN NEXT SLIDE
