In the previous tutorial, we learned about signal behavior and the role of a capacitor in a circuit. A capacitor stores electrical charge in the form of the electrostatic field in response to an applied voltage. It charges whenever the applied voltage increases (relative to the current-voltage across the capacitor) by allowing a charging current…

In the previous article, we presented a resistor selection reference table. With the help of this table, you can determine which type of resistor will be most suitable for a given circuit or application. Once you’ve determined which type of resistor suits the best, it’s time to pick up the desired resistor. For that, it…

The popular Variable voltage regulator IC LM317 can handle only up to 1 ampere current and hence it is not suitable for making a high current variable power supply. This circuit uses IC LM138 to make 1.25 to 28 volts variable power supply with a current up to 5 amps. Circuit working LM 138 is…
