Bharat Financial Inclusion Interview Questions and Answers

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

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 Type Z (very fast tripping).

Relay is an electromechanical device used to control high power electrical devices, while MCB is a circuit protection device that trips in case of overload or short circuit.

• Relay is used to control high power electrical devices by opening or closing contacts based on input signals.

• MCB is a circuit protection device that trips and cuts off power in case of overload or short circuit.

• Relays are electromechanical devices with moving parts, while MCBs are solid-state devices.
