SIMPLE CIRCUITS

An electric circuit is a complete conducting path for an electric current. When the circuit is connected to a

battery, electrons flow from the negative terminal of the battery, through one or more electrical devices, and

then back to the positive terminal of the battery. There are different ways in which circuits can be wired, and

these ways can be described with words or by symbols that are widely known and used. Some of these

symbols are illustrated below.

with 2 cells

The battery pack supplied consists of 4 - 1.5 volt (V) cells connected one after the other. Connecting any

electrical device one after the other is called a "series circuit". Placing the batteries in series results in the

voltages of the batteries to be added, thus the total voltage of the four cells is 6.0 V.

The current which flows through the circuit depends upon the number of electrons flowing through the circuit

per second. When using batteries, increasing the voltage also increases the current in the circuit. An increase

in the current is observed when the brightness of the bulb increases. If any series bulb is unscrewed, an open

circuit is created and no current exists.

Each device placed within the circuit provides a resistance to the electrons flowing through the wire. Some

devices apply greater resistance than others. As the number of devices placed within one series circuit

increases, the resistance also increases. In a parallel circuit, as electrical devices are added the resistance
