12 Ohms 1/4 Quarter Watt Resistor (10 Pieces)

The 12 Ohm 1/4 Watt Resistor (10 Pieces Pack) is a fixed passive electronic component used to control current flow, limit voltage, and protect components in electrical and electronic circuits. This pack contains 10 individual resistors, each having a resistance value of 12 Ohms (Ω) and a power rating of 0.25 Watts (1/4 Watt).

A resistor works by opposing the flow of electric current and converting a small amount of electrical energy into heat. The 12Ω resistance value makes it suitable for applications that require low resistance for current control, load balancing, protection, and signal adjustment.

Specifications

• Resistance Value: 12 Ohm (Ω)

• Power Rating: 1/4 Watt (0.25W)

• Type: Fixed Resistor

• Tolerance: Typically ±5%

• Construction: Carbon Film / Metal Film (depending on model)

Working Principle

The resistor limits the amount of current flowing through a circuit according to Ohm’s Law. When electrical current passes through the resistor, it creates resistance that reduces current flow and produces a small amount of heat.

A 12 Ohm resistor is commonly used in circuits where a low resistance value is needed, such as current limiting, motor control, LED protection, power circuits, and electronic load applications.
