Q2. Parts of transformer and function of each
Ans. 
Transformer parts include core, windings, and insulation. Core provides magnetic path, windings carry current, insulation prevents short circuits.
• Core: Provides magnetic path for flux to flow through

• Windings: Carry current and induce voltage

• Insulation: Prevents short circuits between windings and core

• Examples: E-core, C-core, shell-type transformer

Q3. Types of MCB in electrical system
Ans. 
Miniature Circuit Breakers (MCBs) are types of circuit breakers used in electrical systems to protect against overcurrent and short circuits.
• MCBs are classified based on their breaking capacity, rated current, and number of poles.

• Common types of MCBs include Type B (standard), Type C (medium delay), and Type D (high delay).

• MCBs can also be classified based on their tripping curve, such as Type K (fast tripping) and Typ
