This document discusses series and parallel electric circuits. A series circuit has components connected one after the other so there is only one path for current to flow. If one component fails in a series circuit, the entire circuit fails. A parallel circuit has multiple paths for current and if one component fails, current can still flow through other paths. The key differences are that series circuits have the same current but total resistance is the sum of all resistances, while parallel circuits have the same voltage across all branches but current divides across the paths.

• SERIES AND PARALLEL CIRCUITS

4.  Electric circuits are made up of electrical
components
 These components must be joined together
without any gap in between to form a closed
circuit.

5. Series and Parallel
There are 2 ways in which an
electric circuit can be
arranged:
1. Series
2. Parallel

6. Series circuit
 A route for the flow of electricity that
has only one path.
 A Series circuit is a closed circuit in
which the current follow one path.

7.  A series circuit connects the components one after
the other
 A single loop is formed
 A break in any part of a series circuit stops the
flow of current in the whole circuit.

8. 1. Total resistance (Rt) is equal to the
sum of all the individual resistance.
2. In a series circuit the current flowing
in all parts of the circuit is the same.
3. The sum of the voltage drops in a
series circuit is equal to the applied
voltage.
4. The voltage drop across each
individual resistance depends upon the
value of resistance.

10. if one component in a series circuit fails, then all the
components in the circuit fail because the circuit has
been broken.
DISADVANTAGE

11. A parallel circuit has many paths for
current to travel and more than one
resistor, If one resistor stops working
current will still travel to other resistors
on same circuit.
The voltage across all branches or paths of
a parallel circuit is the same.
PARALLEL CIRCUIT

12. Parallel
• A parallel circuit divides into two or more
branches.
• The current divides and flows through each
parallel branch.
• If a component breaks or is removed, the other
components remain on.
