Faqs

1. How to test/check electronic components?

With a digital multimeter

Resistors: To check the resistance of a resistor, first set the multimeter in resistance mode. Connect the probes to both terminals. The resistance value will be displayed on the multimeter. The value might differ slightly from the exact resistance. For reference, you can use a color code chart.

Capacitors: Set the multimeter in continuity mode. Connect the multimeter leads across the capacitor. If you hear a beep, it means the capacitor is faulty as capacitors do not conduct DC currents.

Diodes: Measure the forward bias voltage with the multimeter in diode mode. It should be between 0.5–0.7 V for a silicon diode and 0.2–0.3 V for a germanium diode. If it displays O.L. or values outside these ranges, the diode may be blown or shorted.

With a circuit board

LED: Build a simple 5V circuit with a 330Ω resistor in series between the power source and the LED (to limit current). Connect ground to the LED’s negative lead. If it glows, the LED is working properly.

Resistance and capacitance can also be checked during device operation by measuring voltage across the leads with a multimeter.

2. How to solder electronic components?

Soldering is the process of joining two or more metal objects together by melting and applying a filler metal (solder) into the joint. The filler metal has a relatively low melting point and creates permanent electrical connections between electronic components.

Tools required for soldering:

Soldering Wire
Soldering Iron
Flux
Soldering Station (optional)
Stand (optional)

3. What are electronic components?

Electronic components are the building blocks of all electronic devices. They include capacitors, resistors, switches, and integrated circuits (ICs). Each component has unique characteristics and functions, but together they form circuits that allow current to flow and devices to operate.

4. Where to buy electronic components online in Bangalore?

Robocraze is a leading provider of electronic components in Bangalore. From ICs to resistors and capacitors, Robocraze offers a wide range of products available for online purchase. Orders above ₹499 qualify for free home delivery, and customers can expect excellent support and competitive pricing for all their DIY and engineering needs.

5. What are passive electronic components?

Passive electronic components do not require external power to operate. They provide functions such as filtering, impedance matching, and energy storage. Common examples include resistors, capacitors, and inductors. These components are essential for stability and control in circuits.

6. Why do we consider only voltage when purchasing electronic components?

Voltage is a critical factor in ensuring that electronic components function correctly. Many components, such as capacitors and semiconductors, are voltage-dependent. Using the proper voltage ensures the device operates safely and efficiently without damage.

7. What are active electronic components?

Active electronic components generate, amplify, or control electrical signals. Examples include transistors, diodes, thyristors, and integrated circuits. They are used for signal processing, amplification, logic operations, and power regulation in both consumer and industrial electronics.

8. What are basic electronic components?

Basic electronic components form the foundation of all electrical circuits. These include resistors, capacitors, transistors, crystal oscillators, diodes, ICs, and connectors. They are widely used across industries such as robotics, automotive, medical devices, and consumer electronics.

9. What materials are used for electronic components?

Electronic components are made from materials such as copper wire, solder alloys (tin-lead or silver-tin), ceramic substrates like alumina (Al₂O₃), silicon and gallium arsenide semiconductors, and printed circuit board materials. These materials are chosen for their conductive, insulating, and thermal properties to ensure efficient and reliable performance.

10. How to prevent power fluctuations from damaging electronic components?

Use an uninterruptible power supply (UPS) with surge protection to safeguard devices from voltage spikes or drops. Installing noise filters on AC/DC inputs and ensuring capacitors are rated appropriately for their application further helps prevent damage. Regular maintenance and system testing can also identify potential vulnerabilities early.

11. How to connect electronic components in a breadboard?

When connecting components in a breadboard, identify each component’s pin configuration and polarity. Connect power (+V) and ground (-V) rails correctly. Use jumper wires to interconnect components, ensuring no short circuits occur. Double-check connections before powering the circuit to prevent component damage.

12. How to store electronic components?

Store components away from heat and humidity. Use labeled containers or anti-static bags for easy identification and protection. Group similar parts together, keep shelves dust-free, and use racks for small components like screws or connectors. Proper organization extends component life and simplifies retrieval during projects.
