# Electronic Projects Using Resistors, Diodes and Capacitors

• XuFyaN
In summary, the conversation revolves around a task to make an electronic project using only resistors, diodes, capacitors, and a power supply. The participants discuss various ideas and limitations, such as the difficulty of understanding complex projects and the availability of an oscilloscope or Vero board. They also consider using logic gates and suggest a diode bridge as a potential project. It is noted that there may be limitations due to only having a DC power supply.

## Homework Statement

We've a task to make a electronic projects using only resistors,diodes and capacitors and a supply , what could we make out of these parts ??

## The Attempt at a Solution

I've searched over internet for 2 days and found 100 of projects but all of them are very difficult to understand because we are still beginner and don't know much about projects and electronic parts except diode, capacitor and resistor.

Wow, not much! Are you allowed to use an oscilloscope to observe the v(t) at different parts of the circuit as you turn the supply on and off? You could show different RC time constants, and voltage divider effects...

yes oscilloscope is allowed to use and our teacher told use to make a project on a Vero board , but we've have never seen any board except bread board ! So rare ! :(
our teacher gave an idea to make project something that uses logic gates ..!

what project using silicon diode we can make ??

its not difficult

you can make diode bridge from these devices. which convert AC voltage to DC.

Well, except for the part where it sounds like they only have a DC power supply to use.

## 1. What is the purpose of resistors, diodes, and capacitors in electronic projects?

Resistors are used to control the flow of electric current in a circuit, while diodes allow current to flow in only one direction. Capacitors store and release electric charge, providing temporary power supply for electronic components.

## 2. Can different types of resistors, diodes, and capacitors be used interchangeably in electronic projects?

No, different types of these components have different properties and functions, so they cannot be used interchangeably. It is important to choose the appropriate type and value for each component based on the specific requirements of the circuit.

## 3. How do I calculate the value of a resistor, diode, or capacitor for my electronic project?

The value of a resistor is determined by its color bands, while the value of a diode can be found in its datasheet. The value of a capacitor is usually marked on the component, but can also be calculated using the formula Q=CV, where Q is the charge, C is the capacitance, and V is the voltage.

## 4. Can I use any type of solder for connecting resistors, diodes, and capacitors in my electronic project?

No, it is important to use the appropriate type of solder for electronic projects, such as lead-based or lead-free solder. This will ensure a strong and reliable connection between components.

## 5. How do I troubleshoot if my electronic project is not working properly?

If your project is not working as intended, first check all connections and make sure they are secure. Then, use a multimeter to test the voltage and resistance at different points in the circuit. If necessary, replace any faulty components or consult a professional for further assistance.
