What is voltage and current in simple words

What is voltage and current in simple words

Voltage - Voltage (Electric potential difference) is defined as the pressure from a power source.Voltage pushes charged electrons (current) through a conductors and enable them to do work such as glowing a light. 
In other words Voltage is a electromotive force that is the cause of electric flow.
i.e- Batteries are the sources of voltage in many electric circuits.
It is defined by Ohm's Law
V=IR
Where 
I=Current measured inAmpere
V=Voltage measured in Volt
R=Resistance Measured in Ohm

Current - Current is rate at which the electrons or electric charge flows through a conducting loop or a electric Circuit. 
It is defined by Ohm's Law
I=V/R
Where 
I=Current measured inAmpere
V=Voltage measured in Volt
R=Resistance Measured in Ohm

How railway system works

Railway systems consist of a network of interconnected tracks, stations, and trains that transport people, goods, and other materials over long distances. The railway system works on the principles of physics and engineering to move trains safely and efficiently along tracks. Here are the basic components of the railway system: Tracks:       The tracks are made of steel rails that are mounted on sleepers or ties. These tracks provide a smooth surface for the trains to travel on. Trains: The trains consist of locomotives, passenger or freight cars, and other equipment needed for operation. The locomotives are responsible for pulling the train along the tracks. Signals: Signals are used to communicate information to train drivers, such as when to stop, slow down, or proceed. They are used to control the movement of trains and ensure their safety. Power: Trains can be powered by electricity or diesel fuel. Electric trains use overhead lines to transmit power, while diesel...

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...
