Q1. What is transformer?
Ans. 
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 in power distribution systems

• Examples include power t...read more

Q2. Types of transformer?
Ans. 
Types of transformers include step-up, step-down, isolation, autotransformer, and instrument transformer.
• Step-up transformer increases voltage

• Step-down transformer decreases voltage

• Isolation transformer provides electrical isolation between primary and secondary windings

• Autotransformer has a single winding with multiple taps

• Instrument transformer is used for measuring current or voltage in high voltage circuits

Q3. What is current transformer?
Ans. 
A current transformer is a type of instrument transformer that is used to measure alternating current.
• Current transformers step down current to a safe level for measurement or protection purposes.

• They have a primary winding connected in series with the circuit carrying the current to be measured.

• The secondary winding is connected to measuring or protective devices.

• Current transformers are commonly used in power systems...read more

Q4. What is difference between current transformer and potential transformer?
Ans. 
Current transformer is used to measure current while potential transformer is used to measure voltage.
• Current transformer is connected in series with the circuit being measured, while potential transformer is connected in parallel.

• Current transformer steps down the current to a measurable level, while potential transformer steps down the voltage.

• Current transformer is used for protection and metering purposes, while po...read more

Q5. What is current
Ans. 
Current is the flow of electric charge in a circuit.
• Current is measured in Amperes (A).

• It is the rate of flow of electric charge past a point in a circuit.

• Current can be either direct current (DC) or alternating current (AC).

• In a series circuit, the current is the same at all points.

• In a parallel circuit, the total current is divided among the branches.

• Ohm's Law relates current, voltage, and resistance: I = V/R.

Q6. What is voltage
Ans. 
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
• Voltage is the driving force that pushes electric current through a circuit

• It is measured in volts (V)

• Higher voltage means more potential energy available to move electrons

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

• Example: A battery provides a voltage of 1.5V to power a flashlight

Q6. What is function on fuse , circuit breaker
Ans. 
Fuses and circuit breakers are safety devices used to protect electrical circuits from overloads and short circuits.
• Fuses are designed to melt and break the circuit when there is an overload or short circuit, preventing damage to the circuit or equipment.

• Circuit breakers are switches that automatically trip when there is an overload or short circuit, cutting off the flow of electricity.

• Fuses need to be replaced after t...read more
