Basic technical, physics, and mathematics questions.

Q1. What is the function of a transformer?
Ans. 
A transformer is an electrical device that transfers electrical energy between circuits through electromagnetic induction.
• Transforms voltage levels: Increases (step-up) or decreases (step-down) voltage for efficient power transmission.

• Used in power distribution: Essential for transmitting electricity over long distances with minimal losses.

• Example: Step-up transformers are used at power plants to increase voltage for t...read more

Q2. What is the difference between Current Transformers (CT) and Potential Transformers (PT)?
Ans. 
CTs measure current, while PTs measure voltage in electrical systems for protection and metering.
• CTs are used to step down high current levels to a manageable value for measurement.

• PTs are used to step down high voltage levels to a lower value for measurement.

• Example of CT: Used in power plants to monitor generator output.

• Example of PT: Used in substations to monitor line voltage.

• CTs provide current input for protectiv

Q3. What is the difference between a fuse and a circuit breaker?
Ans. 
A fuse is a one-time protective device, while a circuit breaker can be reset after tripping due to overload or short circuit.
• Fuses melt to break the circuit, while circuit breakers trip and can be reset.

• Fuses are typically cheaper and simpler, but circuit breakers offer more convenience.

• Example of a fuse: glass tube fuse in household appliances.

• Example of a circuit breaker: automatic reset circuit breaker in electrical
