Q1. Level order traversal of binary tree
Ans. 
Level order traversal of binary tree visits nodes level by level, from left to right.
• Use a queue to keep track of nodes at each level

• Start by pushing the root node into the queue

• While the queue is not empty, dequeue a node, visit it, and enqueue its children

Q1. 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 through a conductor

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

• In a series circuit, the current remains the same throughout

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

Q2. What is voltage
Ans. 
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
• Voltage is the force that pushes electric current through a circuit

• It is measured in volts (V)

• Voltage is the potential difference between two points in a circuit

• Higher voltage means more potential energy available to move electrons

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

Q3. What is vcb full form
Ans. 
VCB full form is Vacuum Circuit Breaker.
• VCB stands for Vacuum Circuit Breaker.

• It is a type of circuit breaker that uses a vacuum to extinguish the arc when the contacts open.

• VCBs are commonly used in medium voltage applications.

• They are more reliable and require less maintenance compared to other types of circuit breakers.

Q4. What is mcb full form
Ans. 
MCB full form is Miniature Circuit Breaker.
• MCB stands for Miniature Circuit Breaker.

• It is an electromechanical device that protects an electrical circuit from overcurrent.

• MCBs automatically switch off electrical circuits during abnormal conditions.

• They are commonly used in residential and commercial buildings for electrical safety.

• Examples of MCB brands include Schneider Electric, Siemens, and Legrand.

Q5. What is transform
Ans. 
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Transformers consist of two coils of wire, known as the primary and secondary coils.

• The primary coil is connected to a power source, creating a magnetic field when current flows through it.

• This magnetic field induces a voltage in the secondary coil, allowing for the transfer of electrical energy.

Q2. How CT and PT will work
Ans. 
CT and PT are used in electrical systems to measure current and voltage respectively.
• CT (Current Transformer) is used to measure high currents by stepping down the current to a manageable level for measurement.

• PT (Potential Transformer) is used to step down high voltages to a safe level for measurement.

• CT and PT are essential components in power systems for accurate measurement and protection.

• Example: A CT with a ratio...read more
