HIRA stands for Hazard Identification and Risk Assessment.

• HIRA is a systematic process of identifying potential hazards and analyzing the associated risks.

• It involves identifying the likelihood and severity of harm that could result from each hazard.

• The purpose of HIRA is to develop appropriate control measures to mitigate or eliminate the identified risks.

• Examples of hazards that may be identified through HIRA include...read more

Risk assessment is the process of identifying, analyzing, and evaluating potential hazards and their associated risks.

• Identifying potential hazards

• Analyzing the likelihood and severity of harm

• Evaluating the level of risk

• Implementing measures to control or mitigate risks

• Reviewing and updating the risk assessment regularly

• Example: Conducting a risk assessment for a construction site to identify potential hazards such as ...read more

NMR stands for Nuclear Magnetic Resonance and FSD stands for Functional Safety Design.

• NMR is a technique used in chemistry and physics to study the properties of atomic nuclei.

• FSD is a process used in engineering to ensure that a system or product is designed to be safe for its intended use.

• NMR can be used to determine the structure of molecules and study chemical reactions.

• FSD involves identifying potential hazards, a...read more

Alternating current (AC) is an electric current that reverses direction periodically, commonly used in power supply systems.

• AC changes direction periodically, unlike direct current (DC) which flows in one direction.

• The frequency of AC is measured in Hertz (Hz); for example, in the US, it's typically 60 Hz.

• AC is used in household power supplies, such as for lighting and appliances.

• Transformers can easily step up or step...read more

Transformers experience various losses, primarily copper and iron losses, affecting efficiency and performance.

• Copper Losses: Caused by resistance in the windings; increases with load. Example: I²R losses.

• Iron Losses: Also known as core losses, consist of hysteresis and eddy current losses. Example: Hysteresis loss due to magnetic properties.

• Stray Losses: Occur due to leakage flux in the transformer; generally small bu...read more

Transformers are classified into various types based on their design, function, and application in electrical systems.

• Step-up Transformer: Increases voltage, e.g., used in power transmission.

• Step-down Transformer: Decreases voltage, e.g., used in power supplies.

• Isolation Transformer: Provides electrical isolation, e.g., used in sensitive equipment.

• Auto Transformer: Has a single winding, e.g., used in voltage regulation...read more

Step up transformer voltage ko badhata hai, jo ki electrical energy ko efficient tarike se transmit karne mein madad karta hai.

• Step up transformer input voltage ko badhata hai, output voltage ko increase karta hai.

• Yeh transformers power transmission mein istemal hote hain, jaise ki power plants se grid tak.

• Example: Agar input voltage 10V hai aur transformer ka turns ratio 1:3 hai, to output voltage 30V hoga.

• Yeh transfo...read more

A diode is an electronic component that allows current to flow in only one direction. To check if it's ok, use a multimeter in diode mode.

• A diode has two terminals: an anode and a cathode

• When forward-biased, a diode allows current to flow through it

• When reverse-biased, a diode blocks current flow

• To check if a diode is ok, use a multimeter in diode mode and measure the voltage drop across the diode

• A good diode will have...read more

Digital refers to discrete values while analog refers to continuous values.

• Digital signals are represented by binary code (0s and 1s) while analog signals are represented by continuous waves.

• Digital signals are less susceptible to noise and interference compared to analog signals.

• Digital devices are generally more precise and accurate than analog devices.

• Examples of digital devices include computers, smartphones, and d...read more
