This document provides an overview of series and parallel circuits, explaining their definitions, current and voltage characteristics, and practical applications. A series circuit allows current to flow through a single path, while a parallel circuit offers multiple pathways, enhancing stability and efficiency. The presentation also highlights common uses for each type of circuit, including in lighting and household electrical systems.

3. What is Series
Circuit?
A series circuit is a circuit in which resistors
are arranged in a chain, so the current has only
one path to take. The current is the same
through each resistor.

5. In a series circuit, the current is the same for all of the elements.
In a series circuit, the voltage is the sum of the voltage drops of
the individual components (resistance units).

6. Series Circuit - Uses
Series circuits are most often used for lighting.
The most familiar example is a string of classic
Christmas tree lights, in which the loss of one
bulb shuts off the flow of electricity to each bulb
further down the line.
However, series circuits can be used for any
situation in which a single cable is used to
supply power to a number of widely spaced
lights or other devices.

7. What is Parallel
Circuits?
A parallel circuit is one that has two or
more paths for the electricity to flow, the
loads are parallel to each other.

9. The current in each individual resistor is found by Ohm's
law. Factoring out the voltage gives
In a parallel circuit, the voltage is the same for all elements.

10. Parallel Circuit - Uses
A parallel circuit is an electrical circuit which has
two or more paths for an electrical charge to flow
through.
The parallel circuit is the standard electrical
circuit found in most homes and devices. Because
it provides more than one way for a current to
flow through to a device, it creates a much more
stable and efficient power system than would
otherwise be possible.
The uses of the parallel circuit are manifold.
