Force Motors Interview Questions, Process, and Tips

SCR is a semiconductor device used for controlling high power circuits.

• SCR stands for Silicon Control Rectifier.

• It is a type of thyristor.

• It is used for controlling high power circuits.

• It has three terminals: anode, cathode, and gate.

• It can be turned on by applying a small voltage to the gate terminal.

• Once turned on, it will continue to conduct even if the gate voltage is removed.

• It is commonly used in power electronic...read more

Primary and secondary I and V of transformer are related by the turns ratio.

• The primary and secondary currents are inversely proportional to their respective turns ratios.

• The primary and secondary voltages are directly proportional to their respective turns ratios.

• The turns ratio is the ratio of the number of turns in the primary winding to the number of turns in the secondary winding.

• The relationship between primary a...read more

Logic gates are electronic components that perform logical operations on one or more binary inputs.

• They are the building blocks of digital circuits.

• There are seven basic types of logic gates: AND, OR, NOT, NAND, NOR, XOR, and XNOR.

• Logic gates can be combined to create more complex circuits.

• They are used in computer processors, calculators, and other digital devices.

• Logic gates operate on binary values, where 0 represen

A flip-flop is a digital circuit that can store one bit of information and has two stable states.

• It is used in digital electronics to store binary data.

• It has two stable states - SET and RESET.

• It can be implemented using logic gates like NAND, NOR, etc.

• Types of flip-flops include SR flip-flop, D flip-flop, JK flip-flop, and T flip-flop.

• Example: A D flip-flop stores one bit of data and has a single input (D) and two out

A bridge rectifier is an electronic circuit that converts AC to DC voltage using diodes arranged in a bridge configuration.

• It is used to convert AC voltage to DC voltage.

• It consists of four diodes arranged in a bridge configuration.

• The output of a bridge rectifier is a pulsating DC voltage.

• It is commonly used in power supplies and battery chargers.

• The bridge rectifier is more efficient than a half-wave rectifier.

• Exampl...read more

Temperature in the range of 1000°C can be measured using thermocouples or optical pyrometers.

• Thermocouples are made of two different metals that generate a voltage proportional to the temperature difference between the two junctions.

• Optical pyrometers measure the intensity of the thermal radiation emitted by the object and convert it into temperature.

• Both methods require calibration and consideration of environmental f...read more
