In many applications, there’s a need for a constant voltage source. However, there are more constant current source applications than constant voltage sources. Most power supplies are voltage sources, including batteries and bench power. A constant current source can be used anywhere a fixed current is required. A resistor can also be used, but the…
How to create a constant current source using LM338
Voltage and current sources are two fundamental types of electrical sources used in electronic circuits. A voltage source, such as a battery, is commonly used in many devices. It’s a two-terminal device that maintains a constant voltage across its terminals, regardless of the current flowing through the source. A current source is typically less discussed…
