What are the resistor values?
What are the resistor values?
A resistor is a device that opposes the flow of electrical current. The bigger the value of a resistor the more it opposes the current flow. The value of a resistor is given in ohms and is often referred to as its ‘resistance’.
How do you use E12 series?
Resistors in the E48 series tend to be used for high tolerance applications. They are much less widely used than E24 and certainly those electronic components in the E12 or E6 series….Resistor E series tables of values.
| E12 Standard Resistor Series | ||
|---|---|---|
| 1.0 | 1.2 | 1.5 |
| 1.8 | 2.2 | 2.7 |
| 3.3 | 3.9 | 4.7 |
| 5.6 | 6.8 | 8.2 |
What is 10 E resistance?
10E =100 ohms. 15E=150 ohms. 22 E = 220 ohms etc.
What color is a 1 ohm resistor?
Brown
Resistor Band Colors

| Brown | 1 |
| Red | 2 |
| Orange | 3 |
| Yellow | 4 |
How will you define 1ohm?
One ohm is equal to the resistance of a conductor through which a current of one ampere flows when a potential difference of one volt is applied to it.
What is preferred value?
In industrial design, preferred numbers (also called preferred values or preferred series) are standard guidelines for choosing exact product dimensions within a given set of constraints.
What is E12 base?
The Candelabra base is also called an E12 base. You usually find that light bulbs with a Candelabra or E12 base are found in chandeliers, small nightlights, and small decorative bulbs. This type of light bulb base is less than half the size of a Medium/E26 light bulb base.
How do you read a SMD resistor?
Reading a SMD resistor code
- the first two numbers indicates the significant digits for the resistance, e.g. “22” indicates 22 ohms.
- the third number will be a multiplier that must be multiplier by the first two numbers, or will indicate how many zeros should be added to the first two numbers.
What is the color code of 0.1 ohm resistor?
0.1 Ohm Resistor Color Code: Brown, Black, Silver, Golden.
What is a 1M ohm resistor?
M (mega) means millions. So, if 1K means 1,000 ohms, 1M means 1,000,000 ohms.
How do you calculate 1k ohm resistor?
So, a 1k Ω resistor has a value of 1,000 ohms and the number we will code is 1,000….Coding a 1k Ohm Resistor
- Step 1: Identify the first and second significant figures.
- Step 2: Count the number of zeros after the first two significant figures.
What do the numbers on an SMD resistor mean?
Standard SMD resistors are labeled with a three-digit code, with the first two digits representing the resistance value’s first two integers and the third digit representing the multiplier, such as x1, x10, x100, and so on. As an example,
What does E12 mean in resistors?
E12 means that every decade (0.1-1.0, 1-10, 10-100, etc.) is divided in 12 steps on a logarithmic scale. The size of every step is equal to: Thus, every value is 21% or 1.21 times higher than the previous value in the series, rounded to whole numbers. Because of this, all resistors with a tolerance of 10% overlap.
What are the standard values for resistors?
By using standard values, resistors from different manufacturers are compatible for the same design, which is favorable for the electrical engineer. Aside from the preferred values, many other standards related to resistors exist. Example include the standard sizes for resistors and the marking of resistors with color codes or numerical codes.
What is the tolerance of E192 resistors?
The most common series are: E192 0.5% (also used for resistors with 0.25% and 0.1%). The E6 series has six values in each decade. The tolerance is ±20%.
