I was interviewed in Jan 2025.
Active power is the actual power consumed by a system, while reactive power is the power that oscillates between the system and the source.
Active power is the real power consumed by electrical devices and is measured in watts (W).
Reactive power is the power that flows back and forth between the source and the load, without performing any useful work.
The combination of active power and reactive power gives the total pow...
Different types of temperature sensors include thermocouples, RTDs, thermistors, and infrared sensors. RTD stands for Resistance Temperature Detector and PT100 is a type of RTD.
Thermocouples: measure temperature based on voltage produced by two different metals joined together
RTDs (Resistance Temperature Detectors): measure temperature by changes in electrical resistance
Thermistors: measure temperature based on changes...
BMS are systems that control and monitor building operations, such as HVAC, lighting, and security, to improve efficiency and occupant comfort.
BMS integrate various building systems to centralize control and monitoring.
They use sensors and actuators to collect data and adjust settings based on predefined parameters.
BMS can optimize energy usage, reduce maintenance costs, and improve occupant comfort.
Examples of BMS inc...
Forward flow is the direct action of the controller on the process, while backward flow is the feedback from the process to the controller in a PID control system.
Forward flow is the control action that directly affects the process based on the setpoint and error signal.
Backward flow is the feedback mechanism where the process output is compared to the setpoint to generate an error signal for the controller.
In a PID co...

Very friendly interviewer. Just focus on basic things.
An operational amplifier is a high-gain electronic voltage amplifier with differential inputs and a single output.
Operational amplifiers are commonly used in analog circuits for signal processing, filtering, and mathematical operations.
They have a very high input impedance and a very low output impedance.
Op-amps can be configured in various ways such as inverting amplifier, non-inverting amplifier, summing amplifier, i...
A transistor is a semiconductor device used to amplify or switch electronic signals.
Transistors are fundamental building blocks of modern electronic devices.
They can amplify electrical signals, control the flow of current, and act as switches.
There are two main types of transistors: bipolar junction transistors (BJTs) and field-effect transistors (FETs).
Transistors are used in a wide range of applications, from compute...

Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.
Ohm's Law is represented by the formula V = I * R, where V is the voltage, I is the current, and R is the resistance.
It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.
For example, if a circu...
