 BASIC ELECTRICAL QUESTIONS 



Q1. What is potential Potential difference?
Ans. It is defined as the work done to Move a unit charge from one point to another points.It is measured by voltmeter and always connected in parallel.it is also called electric pressure and electric tension.
Potential difference =Work done /Charge
V=W/Q volt 

Q2. What is anode and cathode means in electricity?
Ans.Positive terminal is called cathode and Negative terminal is called anode.

Q3. How electric current is generated? 
Current can be generated by moving a Metal wire through a magnetic field.
i.e - Generator rotates a coil of wire through a magnetic field. 

Q4. What does one volt means? 
One Volt can be defined as the energy consumption of one joule per charge of one coulomb. 

Q5.How voltage is measured in a circuit? 
A voltmeter is always connected in parallel in circuit to measure the potential difference between two points

25 Basic Pneumatics Interview Questions You Must Know (For Freshers & Beginners)

🛠️ PNEUMATICS INTERVIEW QUESTIONS – BASIC LEVEL (1 to 25)   1. Pneumatics kya hota hai? Answer: Pneumatics ek technology hai jisme compressed air ka use karke mechanical motion generate kiya jata hai. Yeh mostly automation systems, machinery, aur tools mein use hoti hai.   2. Pneumatics aur Hydraulics mein kya difference hai? Answer: Pneumatics mein air use hoti hai jabki hydraulics mein oil. Pneumatics systems light aur fast hote hain, lekin hydraulics zyada force generate kar sakta hai.   3. Compressed air ka pressure kitna hota hai industry mein? Answer: Normally 6 to 7 bar (approx. 90 to 100 PSI) tak ka pressure use hota hai general industrial pneumatic systems mein.   4. Pneumatic system ke main components kaun se hote hain? Answer: Compressor, air filter, regulator, lubricator (FRL unit), valves, actuators (like cylinders), pipelines, aur fittings.   5. Compressor kya karta hai? Answer: Compressor ambient air ko suck ka...

What are the causes if lube oil found in fuel

H ere's a concise explanation for each possible cause of lube oil found in the engine fuel: 1. Faulty Injector Cups: Worn or damaged injector cups can lead to lube oil from the engine's lubrication system seeping into the fuel system during injection, causing oil contamination in the fuel mixture.   2. Failed Fuel Injector Seals: Seals on the fuel injectors that have deteriorated or failed can allow lube oil to enter the fuel system, resulting in oil mixing with the fuel during injection. 3. Leaking Fuel Injector O-Rings: Damaged or worn O-rings on the fuel injectors can permit lube oil leakage into the fuel system, contributing to oil contamination of the fuel.   4. Fuel System Contamination: Contaminated fuel or debris within the fuel system can mix with lube oil, leading to oil contamination of the fuel supply that enters the engine. 5. Faulty Fuel Pump Seals: Worn or damaged seals within the fuel pump can enable lube oil to mix with the fuel during pumping, ...
