Q2. Define the ohm law
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.
• Ohm's Law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• It is named after the German physicist Georg Simon Ohm w

Q1. What is voltage define it?
Ans. 
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
• Voltage is the force that pushes electric current through a circuit

• It is measured in volts (V)

• Voltage is the potential difference between two points in a circuit

• Higher voltage means more energy available to move electrons

• Voltage can be DC (direct current) or AC (alternating current)

Q1. What is mechanism in Hydraulic press
Ans. 
The mechanism in a hydraulic press is the system of components that allows for the transmission of force through a fluid to generate a large amount of pressure.
• Hydraulic press uses a hydraulic cylinder to generate force.

• The force is transmitted through a fluid, typically oil or water.

• The mechanism includes valves, pumps, and pistons to control the flow of the fluid and generate pressure.

• The pressure created by the mech...read more

Q2. What is the method of forging
Ans. 
Forging is a manufacturing process involving the shaping of metal using localized compressive forces.
• Heating the metal to a high temperature to make it more malleable

• Applying compressive forces to shape the metal into the desired form

• Cooling the forged metal to strengthen it

• Types of forging include open-die forging, closed-die forging, and seamless rolled ring forging
