Introduction
A voltage source can be changed into a current source by using ohm's formula, I=V/R. Let's do an actual example to demonstrate the mathematics of ohm's law, using the circuit shown below:. In this Instructable, I will show you how to convert a computer power supply into a regular DC power supply with 12, 5 and 3. As shown in Figure 1, analog control uses discrete components such as resistors, capacitors and operational amplifiers to generate a control effort, u(t).
