2. Simple Circuits • simple circuits is fundamental to understanding electricity and electronics. • The components of Simple Circuits is • Switch, lamp and battery • This is the labeled diagram

3. There are two type of circuits Series Circuits and Parallel Circuits • 1)Series Circuits: is a circuit which has one current paths for electrons. • 2) Parallel Circuits: is a circuit which has more than one current paths for electrons.

4. labeled diagram of a Series Circuits and Parallel Circuits. • Series Circuits: • Parallel Circuits:

5. In Series Circuits: • 1: I is the same. • 2:Vsoursce= V1+V2+V3 • 3:Requialent=R1+R2+R3

6. The Real life application of the Series Circuits: • Is a light on the Christmas tree, • If we take one light of this tree the hole lights will turn off because it is on one path so It is series circuit .

7. Example Problem: • A 10-􏰃, 15-􏰃, and 5-􏰃resistor are connected in a series circuit with a 90-V battery. What is the equivalent resistance of the circuit? What is the current in the circuit? Find Voltage drop across R3 • R equivalent=R1+R2+R3 R equivalent=5 +10 + 15 =30􏰃 • I= V source / R equivalent I=90/30=3A • Voltage drop across R3 V3 = I*R3 3 *15= 45v

8. The advantage of the series circuit is: • 1.Uses less current • 2. R equivalent is high

9. Disadvantage of the series circuit is: • 1)When component become faulty , the circuit become an open circuit and so no current will flows.
