This document discusses different types of electrical circuits. It explains that a series circuit has all components connected one after the other, so if one component fails the entire circuit is broken. A parallel circuit gives each component its own circuit from the battery, so if one component fails the others will remain lit. The document also notes that homes use parallel circuits because if one device fails it does not disrupt power to other devices.

1. Unit 5
FORCES AND ELECTRICITY

2. Starter: Identify the Symbol
battery
closed
switch
voltmeter bulb
ammeter
open
switch

3. A simple
circuit

4. How can you
connect one
more bulb in
the circuit?

5. Learning
objective
To understand
the different
types of circuits.
• Series circuit
• Parallel circuit

6. Series circuit
All the
components are
connected one
after the other.

8. One lamp burns out , none of the lamps will work.

9. Key points:-
Current is the
same all the way
round the
circuit.
Voltage is shared
among the
components.

10. Parallel
circuit
Each component has its own
circuit with battery.

11. Even if one
lamp burns
out rest of
the lamps
will stay
alight.

12. Key points:-
Each pathway
receives the full
circuit voltage.
Current is
shared between
the components.

13. Which type of circuit is used in
our home? Why?
Parallel
circuit

14. How will the brightness
of the lamps be
affected in series and
parallel connections.?

15. Draw a circuit with two parallel
branches, each branch having two lamps
connected in series.
