Hello guys, Today we are discussing the ballast resistor with intensive detail and briefly covering the topic of working the resistor, the Application of the Ballast resistor, and the advantages and disadvantages of the ballast resistor.People use a ballast resistor to limit the current flow in a circuit. They commonly use it in automotive and electronic applications to control the amount of current flowing through a specific part of a circuit.
What is a ballast resistor?
A ballast electrical resistor limits the current flow in a circuit. People typically use it in automotive and electronic applications to control the amount of current that flows through a specific part of a circuit.
In the context of automotive applications, a ballast resistor is often used in the ignition system to regulate the current flow to the ignition coil. The ballast resistor reduces the voltage to the coil when the engine is running, which prevents the coil from overheating and prolongs its lifespan.
Electronics enthusiasts use ballast resistors to stabilize the current flow in a circuit by providing a fixed amount of resistance. LED circuits frequently incorporate them to limit the current flowing through the LEDs and protect them from damage caused by excessive current flow.

Working of the ballast working
Another important application of ballast resistors is in electronic circuits that use LEDs. Specifically. LEDs are diodes that emit light when a current flows through them; however, they are also incredibly sensitive to changes in the amount of current that flows through them.
Consequently, too much current can cause an LED to overheat and become damaged. Conversely, too little current can result in a dim or non-functioning LED circuit often using a ballast resistor to regulate the current flow and safeguard the LEDs from harm. They place the resistor in series with the LED. Designers set the resistor’s resistance to limit the current flow to a safe level for the LED. They determine the resistor’s value based on the forward voltage drop of the LED and the desired current flow through the LED.
