What is a 5k1 resistor?
What is a 5k1 resistor?
Resistors are often marked using the letter k (or letter M) instead of the decimal separator, so 5k1 means 5.1kΩ or 5100Ω, while for example 1M2 means 1.2MΩ. A unique letter for each type of element can substitute for a decimal point in small values. For example, 6R8 is used to indicate a 6.8 Ω resistor.
What does 2k2 resistor mean?
A 2k2 resistor, is a 2.2K resistor, is a resistor with a resistance of 2.2*103 = 22*102 = 2200 ohms = 2200 Ω. This particular resistor is easy to identify visually because it has three red stripes on it.
What does M mean in resistors?
These are Resistance values. Usually valued in Ohms, which is represented by the “Omega” character. K(ilo) mean “Thousand” so 1K Ohms means 1000 Ohms, M(ega) means Million, so 1M means 1 Million.
What does a 100 ohm resistor do?
Commonly used in breadboards and other prototyping applications, these 100 ohm resistors make excellent pull-ups, pull-downs and current limiters. These thick-lead versions of the resistors fit snugly into a breadboard with very little movement, so you should have few to no issues using them in your next project!

What does 1k ohm mean?
One kiloohm is equal to 1,000 ohms, which is the resistance between two points of a conductor with one ampere of current at one volt.
What is a 1k resistor used for?
The 1k resistor is a pull-down resistor. Not the weakest one of that, but that’s okay. It is meant to pull the base of the transistor to a known state (ground) when the control signal is missing/open/high input.
How is a 3.9 K resistor color code?
3.9K Ohm 0.5W Metal Film Resistor (MFR) with ±1% Tolerance. 3.9K Ohm Resistor Color Code: Orange, White, Black, Brown, Brown.
What is resistor formula?
To calculate the total overall resistance of a number of resistors connected in this way you add up the individual resistances. This is done using the following formula: Rtotal = R1 + R2 +R3 and so on. Example: To calculate the total resistance for these three resistors in series.
Why do resistors decrease resistance in parallel?
Adding more resistors in parallel is equivalent to providing more branches through which charge can flow. Even though the added branches offer resistance to the flow of charge, the overall resistance decreases due to the fact that there are additional pathways available for charge flow.
How do you calculate resistors in parallel?
4. “You can find TOTAL RESISTANCE in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 + ” Before we get into the calculations, remember what we said at the start of this section: “The total resistance of a parallel circuit is NOT equal to the sum of the resistors (like in a series circuit).
What happens when you add resistors in series?
In a series circuit, adding more resistors increases total resistance and thus lowers current. But the opposite is true in a parallel circuit because adding more resistors in parallel creates more choices and lowers total resistance. If the same battery is connected to the resistors, current will increase.
