Electricity. It is difficult to present modern life without this faithful assistant who as on wave of a magic wand forces to buzz mixers and drills, skillfully asks to hum quietly fridges and to begin to boil teapots. Even fiddleheaded bulbs yield to such force. To describe such fascinating and difficult way of electricity, people thought up the scheme. How to draw the electric circuit on a usual leaf?

Instruction
1. Sort out, from what consists electric scheme. Divide separate elements of the scheme into three groups. Carry those which develop the electric power (power supplies) to the first, – elements which are called electroreceivers (household appliances) and to the third group carry elements on which current runs to the purpose (wire) to the second.
2. Start drawing of the most widespread and simple electric circuit as connection. Represent the elements connected to a chain one after another. At first draw a horizontal line. Divide it conditionally in half. In each of halves draw the small rectangles located in the middle of pieces. It will be resistors – elements which give some resistance. They can often be met in switches with brightness control of a bulb – the muffled or hurting eyes. Over figures put down figures – define the sequence of connection of resistors. Specify the direction of current by an arrow over a horizontal line.
3. Draw the electric circuit representing parallel connection of two conductors. Draw a rectangle. On the top and lower parties of a figure represent resistors in the form of small rectangles. Close to external borders of figures finish drawing the arrows symbolizing the direction of current. Put down figures. Draw the horizontal lines located from the left and right parties of a rectangle.
4. Draw the electric circuit in simpler way by means of specialized computer programs. They will allow you to draw very difficult electric circuits according to GOSTovskiy standards.
5. Consider that the image of electric circuits has to be with use of the international symbols of a certain size and a form.
