• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of iron or other magnetic materials.

• Transformers are essential in transmitting electricity over long distances efficiently.

• Examples of transformer...read more

CCM stands for cubic centimeter, a unit of volume measurement commonly used in injection moulding.

• CCM is used to measure the volume of material that can be injected into a mould cavity.

• It helps in determining the size and capacity of the moulding machine.

• CCM is crucial in ensuring accurate and consistent production of plastic parts.

• For example, a mould cavity may have a volume of 100 ccm, meaning 100 cubic centimeters of material can be injected into it.

The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.

• Energy is conserved in a closed system

• Energy can be transferred between different forms (e.g. heat, work)

• The total energy of a system remains constant

• Mathematically expressed as: ΔU = Q - W, where ΔU is the change in internal energy, Q is heat added to the system, and W is work done by the system

The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.

• Entropy tends to increase in a closed system

• Heat energy naturally flows from hot to cold objects

• Efficiency of energy conversion processes is limited by the second law

Types of protection in electrical engineering

• Overcurrent protection: protects against excessive current flow

• Overvoltage protection: safeguards against high voltage levels

• Undervoltage protection: prevents damage from low voltage levels

• Short circuit protection: detects and interrupts short circuits

• Ground fault protection: detects current leakage to ground

• Arc fault protection: detects and mitigates arc faults

• Thermal protection: prevents overheating of electrical components

• Transi...read more

Data entry involves accurately inputting information into a database or system.

• Ensure accuracy by double-checking entries

• Use software programs like Microsoft Excel or database systems

• Follow specific guidelines for formatting and organizing data

• Avoid typos and errors by proofreading entries

• Maintain confidentiality of sensitive information

A generator is a device that converts mechanical energy into electrical energy.

• Generates electricity through electromagnetic induction

• Common types include diesel generators, gas generators, and wind turbines

• Used in power plants, homes, and businesses for backup power

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

• Consists of two coils of wire, known as primary and secondary coils

• Primary coil receives electrical energy and creates a magnetic field

• Magnetic field induces a voltage in the secondary coil, transferring energy

• Used to step up or step down voltage levels in power distribution

• Examples include power transformers in substations and voltage converters in electr...read more

Types of welding include MIG, TIG, stick, and flux-cored welding.

• MIG welding uses a wire electrode and shielding gas.

• TIG welding uses a tungsten electrode and inert gas.

• Stick welding uses a consumable electrode coated in flux.

• Flux-cored welding uses a tubular wire filled with flux.

• Other types include spot welding, laser welding, and resistance welding.
