The engine is a machine that converts fuel into mechanical energy to power vehicles, machines, or equipment.

• Converts fuel into mechanical energy

• Powers vehicles, machines, or equipment

• Can be internal combustion engine or electric motor

A wire bonding machine is a tool used in semiconductor manufacturing to connect wires to semiconductor devices.

• Wire bonding machines use heat, pressure, and ultrasonic energy to bond wires to semiconductor devices.

• There are different types of wire bonding machines, such as ball bonding and wedge bonding machines.

• Wire bonding is a crucial step in the production of integrated circuits and other semiconductor devices.

Tolerance refers to the acceptable range of variation in a physical dimension or property of a material or product.

• Tolerance is the difference between the maximum and minimum limits of a dimension or property.

• It ensures that parts fit together properly and function as intended.

• Tolerance can be specified as a numerical value or a range, such as +/- 0.1mm.

• Examples include the tolerance for the diameter of a shaft or the

The least count of a micrometer is the smallest measurement that can be read on the scale.

• The least count of a micrometer is typically 0.01mm or 0.001mm depending on the type of micrometer.

• It is determined by the number of divisions on the thimble and the main scale.

• For example, a micrometer with 50 divisions on the thimble and a main scale reading in mm will have a least count of 0.01mm.

A jig is a type of tool used to control the location and/or motion of another tool. A fixture is a work-holding or support device used in the manufacturing industry.

• Jigs are used to guide cutting tools, while fixtures are used to hold workpieces in place during machining operations.

• Jigs and fixtures are commonly used in manufacturing processes such as welding, drilling, and milling.

• Examples of jigs include drill jigs, ...read more

Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's Law is represented by the equation V = IR, where V is voltage, I is current, and R is resistance.

• It is named after German physicist Georg Simon Ohm, who first formulated the law in 1827.

• Ohm's Law is fundamental in the field of electrical engineering and is used to analyze

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease voltage levels in electrical circuits.

• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.

• Step-up transformers increase voltage levels, while step-down transformers decrease voltage levels.

• Transf...read more

Motors convert electrical energy into mechanical energy, while generators convert mechanical energy into electrical energy.

• Motors use electricity to produce motion, while generators use motion to produce electricity

• Motors have a rotor that spins within a stator, while generators have a rotor that is turned by an external force

• Examples of motors include electric fans and washing machines, while examples of generators in
