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.
 How to make the bulb brighter

parallel circuit diagram :

 

 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..

unit19

Unit 19 is about gravitational force and frictional force . In unit 19 we made a parachute and we read many pages of explanation text and do self check.Frictional force can cause problem on car engine to overheat and causes a car to stop.I learned how tread patterns on shoes and car tires could save a person's life ,how fingerprints could help grip something , gravitational force could pull divers downwards,could speed up a skier in the hill skiing ,could pull things down that is all for sumarising unit 19  

making of parachute

As you can see I am making a parachute with plastic bag ,strings and it is tested with a toy( launch the parachute  with a toy tied to it). The making of the parachute ,the objective is to make air resistance and to show how gravitational force work.It was fun making the parachute and launching it to bad my parachute didn't open so it just fall down to the directly to the ground.To be honest I got jealous  of others parachute because my parachute didn't work its like I want to destroy other's parachute but somehow I just keep it inside because  I want a 9 or a 10 in six pillars.  

science annual project

I made a miniature Monas for my annual project it was not really fun because I had to make my own Monas
it was me vs my own group 1 vs 6 members not really fair but somehow I dont really care.The Monas is made with materials which is easy to find in stores.I was about to post a picture of monas here but because of lazynessI dont really want to do it peace out yo (-_-) !!!!!

science and math fun fair

I really enjoy the math and science fun fair.It was fun playing with friends. I like the games especially tug of war and from trash to treasure which is picking up trash  and putting it in buckets and competing with friends. But unfortunately my group and I has to wait for 15 minutes to play almost all the games and it was really annoying thank you for reading this entri.

Inflating a balloon with vinegar with baking soda

                This are pictures of my group when we are inflating a ballon using vinegar and baking soda . I was quite nervous and thought that it wouldn't work but it actually works. Its really cool but because of the vinegar it stinks.And I am happy I get a inflated balloon attached to an aqua bottle that has a mixture of vinegar and baking soda which is pushing C02 to the balloon.

Introduction

Hello my name is kim on I am the creator of this blog.I am happy that I could make this blog with my friends helping me. I was having a fun time working on this blog and I enjoy making this blog .I hope everybody in this world could see my blog.I am a very playful student at Binus international school Serpong.I like to play computer games and traditional games and I will tell more information about me in 2 years or maybe three in three years time.
