Analog signals can have an infinite number of possible values, while digital signals have a limited number of discrete values (
- Q3. How to check resistance and capacitor faulty?
- Ans.
Resistance and capacitor faults can be checked using a multimeter.
Use a multimeter to measure the resistance of a resistor. A good resistor will have a resistance value within its tolerance range.
For capacitors, check for any physical damage such as bulging or leaking. Use a multimeter in capacitance mode to measure the capacitance value.
In case of capacitors, also check for any signs of overheating or burning marks on...
- Q4. How to convert high voltage to low voltage in DC supply?
- Ans.
High voltage can be converted to low voltage in DC supply using a voltage regulator or a voltage divider circuit.
Use a voltage regulator such as a buck converter to step down the voltage
Implement a voltage divider circuit using resistors to reduce the voltage
Choose the appropriate components based on the input and output voltage requirements
Ensure proper heat dissipation to prevent overheating of components
- Q5. Which component use to convert high voltage to low voltage in DC supply?
- Ans.
A step-down transformer is used to convert high voltage to low voltage in DC supply.
Step-down transformer is commonly used for this purpose
It reduces the voltage while maintaining the same frequency
Examples include power adapters for electronic devices
- Q6. What is role of flux in soldering?
- Ans.
Flux in soldering helps to remove oxidation from the metal surfaces being joined, allowing the solder to flow more easily and create a strong bond.
Flux cleans the metal surfaces by removing oxides, dirt, and other contaminants.
It promotes wetting, which helps the solder to flow and bond properly.
Flux also prevents oxidation of the metal surfaces during the soldering process.
There are different types of flux such as ros...

Interview Preparation Tips
On the starting date you'll again message one person(Yashima Kamra) on Skype, they'll give you 'Zulip'(it's an open source chat system, interface is kind of like Discord but too basic) access. Now you need to message in an assigned group in Zulip. The Zulip part is 'Training' in real but good luck getting any support from the other person. He/she will just give you commands, and if you ask any questions or ask for assistance to understand the new process they'll simply ignore that.
Then if you're lucky like me one day they'll report that you're ate fault, you haven't reported so they've revoked your Zulip access.
I have joined there or you can say hoped to work atleast(as it was 4 hours/day job) but that's not possible it seems.
If you're looking for jobs here I'd suggest to give it a try ofcourse so that people can actually know about this company's rubbish people.
