Big Version of 1 Ohm Smd Resistor That Provides 1 Ohm Resistance Without Using Any Electronic Components.

About: I am interested in electronics and mathematics.

In real life smd resistors are very small of dimensions nearly 0.8mmx1.2mm. Here, I am going to make a big smd resistor which is very huge as compared to real life smd resistor.

Step 1: Introduction

Let's start with an introduction. So, smd resistors are small version of resistors(having very small dimensions) used in electronic circuits.They work similarly as a normal resistor do. Here, I am come with a Big size smd resistor of 1 ohm. In this Big size smd resistor, I am going to use paper circuit technology. In paper circuit technology we use a hard paper and create a resistance. Using this we can make any resistor of values such as 1k, 1ohm, 2ohm and so on. In this instructable I am going to make a Really Big size smd resistance(of large dimension) as compared to normal smd resistor.

So, I am going to make a big size smd resistor of 1 ohm. So let's start.....

Step 2: Tools and Material Required.

1. 1 carton box(as big as you want the smd resistor to be).

2. 2 Electrical wires(more than the half of the length of the box).

3. 1 hard paper.

4. 1 pencil.

5. 1 wire cutter.

6. Aluminium foil.

7. Black Paper.

8. White paper.

9. Multimeter.

10. stapler.

11. White tape.

Step 3: Making the Paper Resistor.

First of all, take a hard paper as shown in diagram. Now, daken the center area of the hard paper as shown in the third diagram.

Step 4: Connecting the Wires to the Paper Resistor.

First of all, take both the wires and connect one end of both the wires to the black and red pins of the multimeter respectively as shown in the second image. Now, put both the wires to the over the paper resistor we made in the first step. But, be sure there is a gap between both the wires. Now, fold the paper from the center as shown in the image. Now, staple it so that the wire cant't move and touch the paper resistor. as shown in the image.

Step 5: Making the Resistance Value to 1 Ohm or Very Near to 1 Ohm

Now, set the resistor to read resistance, the reading maybe not as you want. No problem, fold the paper tightly from the center to make a square paper and apply the tape. Again if you not get the appropriate value then try more tight folding and applying more tape so till you get the 1 ohm resistance or very near to 1 ohm as shown in the figure. After some tight folds, I get a fluctuating value from 0.9ohm to 1.1ohm as shown in figure. In the next step we will try to get 1 ohm.

Step 6: Making Fluctuating Value to Perfect 1ohm Value

Put the paper resistor you made inside the center of the box and press it tightly and when you get the stable 1.0 ohm then stick the resistor in the box at the center as shown in the image. After, placing the resistor tightly in the box I achieve the value of 1.0 ohm as shown in the image. Make the holes in the box in center at both ends. Now, remove the ends of the wire from the multimeter and take out that ends out from both ends of the box from the holes as shown in the image.

Step 7: Packing the Box.

Now, put some folded newspapers so that there is no way for paper resistor to move. now pack the box in the shape of an smd resistor as shown in the images.

Step 8: Make the Silver Lining of the Smd Resistor

Now, except the copper portion of the wire stick the extended wire to the box as shown in the image. Now, here we are going to use the aluminium foil as aluminium foil is conductive in nature. Now, wrap both the ends of the box with the aluminium foil in such a way that the foil touches the copper of the wire as shown in the image, so that when we check the resistor value at both the silver ends we get 1.0 ohm.

Step 9: Making the Upper Black Portion of the Smd Resistor.

Now, Stick the black paper on the top of the box as shown in the image.

Step 10: Making Our Big Smd Resistor to Look Like the Real Dimension Smd Resistor

Now take the white paper and stick it with glue as shown in the images. You can take a real dimension smd resistor or an image of that from google for reference.

Step 11: Measuring the Resistance From the Silver Lining.

Now, measure the resistance from the silver lining at both ends from the multimeter as shown in the image. You get 1.0 ohm.

Step 12: Final Touch

Now, every smd resistor has a code that describes its value. For, 1.0 ohm the code is 1R0.So, we have to write the code 1R0 between the black portion as shown in the images.

Step 13: Final Testing

Now, take the multimeter and finally test the resistor value as shown in the images. Now our big 1.0 ohm big resistor is ready and very large as compared real life smd resistor.
