Mostly Asked Electrical engineering Interview Questions with Answers
Q: What is an electric circuit?
A: An electric circuit is a path through which electric current flows.
Q: What is Ohm’s law?
A: Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
Q: What is the difference between AC and DC current?
A: AC (alternating current) is a type of current that periodically reverses direction, while DC (direct current) flows continuously in one direction.
Q: What is a capacitor?
A: A capacitor is an electronic component that stores electrical energy in an electric field.
Q: What is a resistor?
A: A resistor is an electronic component that limits the flow of electrical current in a circuit.
Q: What is an inductor?
A: An inductor is an electronic component that stores electrical energy in a magnetic field.
Q: What is a transformer?
A: A transformer is an electronic device that transfers electrical energy from one circuit to another through electromagnetic induction.
Q: What is a diode?
A: A diode is an electronic component that allows current to flow in only one direction.

Q: What is a transistor?
A: A transistor is an electronic component that can amplify or switch electronic signals.
Q: What is a microcontroller?
A: A microcontroller is a small computer on a single integrated circuit that is used to control electronic devices.
Q: What is the difference between a microcontroller and a microprocessor?
A: A microcontroller is a complete computer on a single chip that is designed to perform a specific task, while a microprocessor is a central processing unit (CPU) that is part of a larger computer system.
Q: What is an operational amplifier (op-amp)?
A: An operational amplifier (op-amp) is an electronic component that amplifies the difference between two input voltages.
Q: What is a printed circuit board (PCB)?
A: A printed circuit board (PCB) is a board made of insulating material that has conductive pathways etched onto it to connect electronic components.
Q: What is a multimeter?
A: A multimeter is an electronic measuring instrument that can measure voltage, current, and resistance.
Q: What is the purpose of a fuse in an electrical circuit?
A: The purpose of a fuse in an electrical circuit is to protect the circuit from excessive current flow by breaking the circuit when the current exceeds a certain limit.
Q: What is a sensor?
A: A sensor is an electronic device that detects changes in physical properties, such as temperature, pressure, or light, and converts them into an electrical signal.
Q: What is an actuator?
A: An actuator is an electronic device that converts an electrical signal into mechanical motion or force, such as a motor or a solenoid.

Q: What is a servo motor?
A: A servo motor is a type of motor that is controlled with high precision to achieve specific positions or movements.
Q: What is a stepper motor?
A: A stepper motor is a type of motor that moves in discrete steps, typically used in precision control applications.
Q: What is a feedback system?
A: A feedback system is a system that uses sensors and actuators to continuously monitor and adjust the output of a system based on input signals.
Q: What is a control system?
A: A control system is a system that uses feedback to maintain or achieve a desired state or performance in a dynamic system.
Q: What is signal processing?
A: Signal processing is the manipulation of signals, such as audio, video, or data, to extract useful information or enhance their quality.
Q: What is digital signal processing (DSP)?
A: Digital signal processing (DSP) is the processing of signals using digital techniques, such as digital filtering, compression, or modulation.

A: Power electronics is the study and application of electronic devices and circuits for the control and conversion of electrical power.
Q: What is electric power transmission and distribution?
A: Electric power transmission and distribution is the system of infrastructure that delivers electrical power from generation sources to end users.
Q: What is a power system?
A: A power system is a network of electrical components, such as generators, transformers, and transmission lines, that work together to generate, transmit, and distribute electrical power.
Q: What is electromagnetic compatibility (EMC)?
A: Electromagnetic compatibility (EMC) is the ability of electronic devices and systems to function properly in the presence of electromagnetic interference (EMI).
Q: What is electromagnetic interference (EMI)?
A: Electromagnetic interference (EMI) is the disturbance of electronic signals by electromagnetic radiation from other electronic devices or sources.
Q: What is a ground in an electrical circuit?
A: A ground in an electrical circuit is a reference point that is connected to the earth or a conductive surface to provide a zero-voltage reference.
Q: What is a transient in an electrical circuit?
A: A transient in an electrical circuit is a short-lived burst of electrical energy that can cause damage to electronic devices or disrupt electronic signals.
Q: What is a voltage regulator?
A: A voltage regulator is an electronic component or circuit that maintains a constant voltage output, even when the input voltage fluctuates.
Q: What is power factor correction?
A: Power factor correction is the process of improving the efficiency of electrical systems by adjusting the ratio of reactive power to real power.
Q: What is the difference between power and energy?
A: Power is the rate at which energy is transferred or used, while energy is the capacity to do work or produce heat.
Q: What is a circuit breaker?
A: A circuit breaker is an automatic switch that is designed to protect an electrical circuit from damage caused by excessive current flow.
Q: What is a ground fault circuit interrupter (GFCI)?
A: A ground fault circuit interrupter (GFCI) is a safety device that is designed to protect people from electric shock by quickly interrupting the flow of electricity when it detects a ground fault.
Q: What is a surge protector?
A: A surge protector is an electronic device that is designed to protect electronic devices from damage caused by voltage spikes or surges.
