Nones Interview Questions and Answers

Direct on line starter diagram is a simple starting method for electric motors.

• The diagram consists of a power supply, a contactor, and an overload relay.

• The contactor connects the motor to the power supply when it is energized.

• The overload relay protects the motor from overheating by tripping the circuit if the current exceeds a certain level.

• The diagram is commonly used for small to medium-sized motors.

• It is not suitable for large motors as it can cause a high inrush curren...read more

Star delta starter is used to reduce the starting current of induction motors.

• Consists of three contactors and a timer

• During starting, motor is connected in star configuration to reduce current

• After a set time, contactors switch to delta configuration for normal operation

Fluorescent lamp connection involves a ballast, starter, and two pins on each end of the lamp.

• The ballast regulates the current and voltage to the lamp.

• The starter provides a high voltage to initiate the lamp's arc.

• The two pins on each end of the lamp connect to the lamp holder.

• The lamp holder provides power to the lamp and holds it in place.

• The wiring should be done according to the manufacturer's instructions.

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.

• It is named after Georg Simon Ohm, a German physicist who first formulated this law.

• This law is applicable to all types of circuits, including AC and DC circuits.

• It is used to calculate the current, voltage, or resistance in a ci...read more
