Electric Circuit

An electrical circuit is a path which electrons from a voltage or current source follow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load".

Types of Circuits

A series circuit is the simplest because it has only one possible path that the electrical current may flow; if the electrical circuit is broken, none of the load devices will work. The difference with parallel circuits is that they contain more than one path for electricity to flow, so if one of the paths is broken, the other paths will continue to work.An electrical circuit is any closed loop that allows a flow of electrons from a source of current to deliver energy or perform work and then return to the source.
Something that is called a "conductor" allows electric currents to flow through it (e.g. insulated copper wire) from a supply of energy which could, for example, be a battery.
On the subject of holes: They are a free space for another electron to take. It is like asking all the school children in an exam to move one chair forward, and the hole is the empty chair until another kid takes his place. They are particularly important in semiconductor physics.
If you speak to a technician who works in the industry, they might tell you it flows from positive to negative, because this is the conventional direction of current flow. It is a convention left from the days when electricity was first discovered.

 In the making of the electric circuit i was happy i could do it with my friends it was fun i thought i could finish it with my friends but then it turns out differently my friends didn't help me in the series circuit and they tried to make fire by connecting the wires of the battery pack the plus and the min and they made me furious and in the next day in the making of the parallel circuit it is the same no helping and they finished the batteries power so I have to buy a new one and the one that made me really mad is that they don't want to pay the fine (Rp.28.000) that all for the reflection of the electric circuit making Sorry  I dont have the 3 pictures pls give me a (3) (-_-)

the material that we need are:
-6 bulbs
-some wires
-15 alligator clip
-2 casing
-5 batteries
-scissor
-4 bulb casing with the bulb

Steps of the experiments :
first connect the alligator clip to the wires
second put the batteries inside the casing
clip the alligator clip to the wire of the casing
then put the bulbs into the casing and clip it into the alligator clip

that is for series circuit the parallel circuit is almost the same as the making of the series circuit


conclution:
the light bulb glow brighter in the parallel circuit compairing to the series circuit.
the light bulb only glows in the closed circuit..
