50 Pieces 1.2 ohm 1/4W 5% Resistor

Description

1.2 ohm resistor 1/4w 1/4 w 5%

Tutorial: How to use 1.2 ohm resistor

The 1.2 ohm resistor is a fundamental component to regulate the electrical current in Arduino circuits. Ideal for beginners learning the basics of electronics.

What you need

• Current regulation
• Power limitation
• Voltage dividers

Steps

1. Check the resistance and value on a multimeter or read the band color if it is not labeled.
2. Connect the red end of the conductor to the terminal of the Arduino.
3. Connect the other end of the resistor to the desired circuit, following the electrical topology.
4. Ensure that the current value does not exceed 250mA to guarantee the safety of the component.

Mini project

Create a simple voltage divider with an additional resistor. Measure the voltage difference between the two resistors.

Common mistakes

• Using a resistance that is too low, which could cause an overload of the circuit.
• Not checking the resistance value before use.
• Ignoring heat dissipation and using a resistance in dangerous conditions.

Recommended accessories

• Digital Multimeter
• Arduino Uno R3
• Colored Conductors
• Arduino Basic Kit

Frequently asked questions

How hot can the resistance get during use?
Check the datasheet for the maximum power dissipation value.

Can I use this resistance in a low voltage circuit?
Yes, but make sure the current does not exceed 250mA to avoid damaging the component.
