Customer ServiceBy placing a resistor in series with the load, the current flowing through the circuit can be limited.

Customer ServiceCurrent Limiting Resistors Current limiting resistors are one of the simplest forms of current limiting. By placing a resistor in series with the load, the current is restricted based on the resistor’s value, which creates a voltage drop proportional to the current according to Ohm’s Law (V = IR).
Transistors can be used to limit current by controlling the voltage across the load. A transistor can be set up to conduct when the current surpasses a certain threshold, reducing the load voltage and consequently the current. This method is often used in conjunction with feedback mechanisms to dynamically adjust the current.
There are several methods to implement current limiting in electronic circuits: Resistors are the simplest form of current limiting devices. By placing a resistor in series with the load, the current flowing through the circuit can be limited. However, this method is not efficient for high-power applications due to power dissipation concerns.
A simple example is a resistor in series with an LED. You would usually want to have a current limiting resistor in series with your LED so that you can control the amount of current through the LED. If too much current is going through your LED, it will burn out too fast.
Since there is a 2 volt drop over the LED, there will be a 3V drop over the resistor. Ok, so we have 3V and we want to have 15 mA going through the resistor and the LED. To find the necessary resistor value we use Ohm’s law. this gives us So the necessary value for the current limiting resistor is 200 Ohms.
