☑ What Is The Use Of A Ballast Resistor

Over time the ballast resistor can be damaged by normal wear and tear so there are a few things to look for when you suspect a bad or failing ballast resistor needs servicing. This video explains how the ballast resistor works.

Ballast resistor guide the electrical system is one of the more complex systems and the more misunderstood especially by mopar owners.

What is the use of a ballast resistor. An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit. Mopar muscle magazine. Less well understood is the fact that ballast resistors provide appropriate compensation within a circuit for external demands placed on that circuit.

This simple system is easy for even the novice mechanic to wire. A ballast resistor is a resistor inserted into a circuit to compensate for different changes. A ballast resistor is used in a circuit to limit the current and hence prevent it from over current faults.

Here as the current in the circuit varies and increases above a particular threshold value the resistance also starts to increase. The ballast resistor is a resistor contained in the primary ignition circuit wiring that lowers voltage after the engine is started to reduce wear on ignition components. The ballast resistor is commonly found in older vehicles because they did not have the benefit of circuit boards found in most of todays vehicles.

So if you have a classic car with missing ignition components dont hesitate to replace the coil and ballast resistor yourself. A resistor that has the property of increasing in resistance as current flowing through it increases and decreasing in resistance as current decreases. Use in automobiles as the starter motor begins to crank the engine it causes a significant drain on the battery.

A ballast resistor helps regulate voltage flowing in an electrical system to avoid overloads or battery drainage. Others might give a different answer to the question what is a ballast resistor like this. A ballast resistor is an electronic component that is often used to regulate the current in a circuit.

Certain devices such as fluorescent lamps can exhibit a quality known as negative resistance where an increase in current can result in a decrease in voltage.
