How to use resistors?
Resistors can also be used to pull up or pull down a GPIO pin. A pull up resistor will pull a pin high by connecting a voltage supply to a pin. A pull down resistor will pull a pin down to GND. We used a 10K Ohm resistor with a DHT22 temperature sensor to pull the data pin high using the 3.3V supply.
Do resistors go bad?
If the resistor shows signs of blackening or charring, it may be damaged by excess current flow. A resistor showing blackening or charring should be replaced and discarded. Read the resistor value visually.
How do you determine the size of a resistor?
The size of SMD resistors is indicated by a numerical code, such as 0603. This code contains the length and width of the package. So, the imperial code 0603 indicates a length of 0.060" and a width of 0.030". The SMD package code can be given in either imperial or metric units.
What is resistor in English?
A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.
