How To Make A Simple VARIABLE Current Limiting Circuit for high power Circuit Diagram
How To Make A Simple VARIABLE Current Limiting Circuit for high power Circuit Diagram Figure 1 shows a simple current limiting circuit. As the current through the two diodes in series begins to rise, they begin to conduct. This lowers the voltage at the base of the transistor and thus reduces the amount of current passing through the collector - emitter junction and subsequently to the output.

Audio Amplifiers: Audio amplifiers can benefit from the use of current-limiting circuits to safeguard both the amplifier and speaker against excessive current caused by overload or short circuits. This helps prevent component damage and ensures safe and reliable operation. Design Considerations for Current Limiting Circuit

Current Limiting Circuits: A Complete Guide Circuit Diagram
Connect the current limiter in series between the component that you wish to limit its current and the voltage source. If red clip is connected to posive terminal, the black clip must connected to Vcc of the component. Check before apply some voltage. The photo show I dimming a 3W LED with a current limter.

This is video No 2 where I show you how to build a simple circuit that can limit the current using just 2 NPN transistors and 2 resistors. You can set the c Transistors are used in current limiter circuits, which provide a flexible and manageable method of shielding delicate components from high current. This simple current limiter circuit using transistors secure electronic devices against harm by limiting current to a predetermined amount by leveraging the transistors capacity to control current

Limiting current WITHOUT dropping voltage Circuit Diagram
Simple Current Limit Circuit: This circuit will limit the current through the load to about 50ma. As before when the input to the base resistor is 5V Q1 turns on and current flows through the load. When the input is low Q1 is off and no current flows through the load. GND R2 1K R1 14 LOAD +12V GND 5V Q1 2N3904 Q2 2N3904
