How do I know which end of the resistor to start reading from?
Always read resistors from left to right. – Resistors never start with a metallic band on the left. If you have a resistor with a gold or silver band on one end, you have a 5\% or 10\% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.
How do you tell which is the first band on a resistor?
The first band is the brown band closest to the edge. We look up our resistor color code chart, and find that brown has the 1st significant value of 1 and black has the second significant value of 0. The third band is brown, which means that the multiplier is 1.
How do you find the starting point of a five color band resistor?
The top resistor is very difficult to know what side band is the tolerance. The only great tip for 5 bands resistors, is that Black, Orange, Yellow and White are not tolerance, so in case of all bands being spaced equally and one of those colors being at the side band, it is the first digit of the value.
How do you know which side of a resistor is positive?
Resistors don’t care which leg is connected to positive or negative. The + means where the positive or red probe of the volt meter is to be placed in order to get a positive reading. This is called the “positive charge” flow sign convention.
How do you know which side of a resistor is positive and negative?
Do resistors work in both directions?
Resistors are blind to the polarity in a circuit. Thus, you don’t have to worry about installing them backwards. Current can pass equally through a resistor in either direction. The resistance value is typically written next to the resistor symbol.
Do resistors go on positive or negative?
If you think of the wire as being a pipe electricity flows through, you can think of a resistor as being a narrow part of that pipe, that chokes off the flow. Resistors don’t have positive and negative sides — you can hook them up in either direction and they work just the same.
How can I identify a color in an image?
Use a Color Picker to Select an Exact Color from an Image
- Step 1: Open the image with the color you need to match.
- Step 2: Select the shape, text, callout, or another element to be colored.
- Step 3: Select the eyedropper tool and click the desired color.
How to read resistor values?
Decide which band is the first band.
What does a resistor color code mean?
The resistor color code indicates the electronic value of a resistor. Manufacturers devised the universal electronic color code rating system in the early part of the twentieth century because the bands of color were much easier to read on a small resistor than tiny print, and were also cheaper to produce.
What are the colors of a resistor?
Resistor Color Code Chart and Resistance Calculator. Resistors have standard colors for identification of the resistance value. In order, the colors are: black, brown, red, orange, yellow, green, blue, violet, gray, and white. Reading resistors is a very simple procedure if you use the chart and formula below.
